- DISK MANAGER HELP INFORMATION, REVISION 1.0
-
- #-----------------------------------------------------------------------
- # HELP FOR THE DISK MANAGER MAIN MENU
- #MSG01
- The CONFIGURATION MENU is generally the first option taken from here. This
- menu will allow you to be certain that DISK MANAGER is completely aware of
- the size of the hard disk(s) on your computer.
- The INITIALIZATION MENU performs all initialization, or "low-level-format"
- functions on your hard disk(s). This initialization process is required prior
- to any partitioning or preparation options.
- The PARTITIONING MENU allows you to arrange the size/location of the various
- "partitions" on your hard disk(s). The partitions then become the various
- logical drives (C:, D:, etc.) on your system. This menu also allows you to
- proceed to the PREPARATION MENU, where these partitions are readied for DOS.
- SELECT DRIVE will allow you to select either physical disk, if you have two.
- #-----------------------------------------------------------------------
- # HELP FOR THE INITIALIZATION MENU
- #MSG02
- All hard disks require a "low-level-format" to be written on them before
- they become useable for storing data. DISK MANAGER allows you to create
- that "low-level-format" through a process called INITIALIZATION.
- Generally, you will first want to use the DEFECT-LIST MANAGEMENT menu to
- identify to DISK MANAGER all tracks on your hard disk(s) which contain
- flaws. Then, you will want to use the INITIALIZATION function to actually
- perform the initialization.
-
- NOTE THAT THE INITIALIZATION PROCESS DESTROYS ANY DATA ON THE HARD DISK !
-
- The VERIFY option is available to test the integrity of the low level format.
- #-----------------------------------------------------------------------
- # CONFIRMATION OF THE DEFECT-LIST PRIOR TO INITIALIZATION
- #MSG03
-
- DISK MANAGER uses the defect-list to determine whether any given track
- should be initialized as defective or not. The currently displayed defect list
- should be an accurate replica of the defect-information supplied with the disk
- drive. Otherwise, DISK MANAGER will only mark as defective those tracks
- which have such serious defects that they cannot be properly initialized
- at all. This can possibly cause some defective areas to be used for data
- storage, with the risk of loss of data at some later point in time.
-
- IF THE DEFECT-LIST IS NOT ACCURATE, DO NOT CONTINUE WITH THE INITIALIZATION
- PROCESS UNTIL THE DEFECT-MANAGEMENT MENU IS USED TO CORRECT THE DEFECT-LIST.
- #-----------------------------------------------------------------------
- # HELP FOR CHOOSING WHETHER TO INIT/VERIFY TRACKS, PARTS, OR DISKS
- #MSG04
- INITIALIZATION and VERIFICATION functions can be performed on any of the
- following categories:
- (D)isk--usually used on a new installation in order to subject the ENTIRE disk
- to the verification or initialization process.
- (P)artition--usually used when the integrity of a single partition is in
- question, or if a desired partition is to have a different interleave value
- than other areas on the disk.
- (T)rack--single track initialization/verification can be used as a diagnostic
- procedure if you have troubles installing a disk. (i.e. if you are unable to
- initialize, then verify cylinder 0, head 0, you have a very basic problem
- with the disk subsystem.)
- #-----------------------------------------------------------------------
- # HELP FOR THE DEFECT-LIST MANAGEMENT MENU
- #MSG05
- The GET and WRITE options allow saving/retrieving the DEFECT-LIST to/from
- your DISK MANAGER diskette. The files used are named FLAW1.MAP and
- FLAW2.MAP, and can also be copied to a printer to produce a paper-list of
- defects.
- The CLEAR, ADD, and DELETE options are used to manipulate the
- DISK MANAGER DEFECT-LIST so it agrees with the DEFECT-LIST which accompanied
- your disk drive from its manufacturer. This list may have been on a separate
- sheet of paper, or it may be physically attached to the disk drive itself.
- The SCAN option can be used to create a DEFECT-LIST which lists all tracks
- that cannot be successfully verified. This test will not itself destroy any
- data, however, THE HARD DISK MUST BE INITIALIZED PRIOR TO USING THE SCAN OPTION.
- #-----------------------------------------------------------------------
- # DOES THE PARTITION TABLE NEED MODIFICATION?
- #MSG06
- A new disk installation will have NO VALID PARTITION TABLE, and you must
- respond "Yes" to this prompt to create a NEW PARTITION TABLE.
-
- If you have already established a partition table, but wish to change the
- type, select as boot, or otherwise rearrange the partition assignments, you
- will also want to respond "Yes".
-
- If you wish to leave the current PARTITION TABLE as it is, you may respond
- "No" to this prompt, and you will continue into the PREPARATION MENU.
- #-----------------------------------------------------------------------
- # HELP FOR THE PREPARATION MENU
- #MSG07
-
- Preparation of a partition is equivalent to the DOS "FORMAT" process. This
- MUST be performed on all partitions of type DOS, WRITE-READ, or READ-ONLY, or
- DOS will not be able to store files on them.
-
- The legitimacy of the "PREPARATION" can be CHECKED with the (C) option. Also,
- the text in the partition table under NAME-VER column will indicate
- "UNPREPARED" if the preparation has not been performed.
- #-----------------------------------------------------------------------
- # DO YOU WISH TO USE THE DEFAULT PARTITION TABLE ?
- #MSG08
- DISK MANAGER can allocate PARTITIONS which subdivide a physical hard disk
- into multiple regions. Each region, called a PARTITION, is accessed under
- DOS as a UNIQUE DRIVE-LETTER (C:, D:, E:, etc.). These drive letters are ALL
- equally capable of containing programs, data files, etc.
- You can allocate partitions by specifying either MEGABYTES or CYLINDERS.
- Most installations require 1 type DOS partition on the first disk. This
- partition must be smaller than 33.5 MB total size, and will usually be the BOOT
- partition. (NOTE: This 33.5 MB limitation does not exist on DOS versions 4.xx)
- If you have a NONSTANDARD disk drive, this partition will use ONLY
- those heads and sectors specified by the BIOS SETUP of your computer. If heads
- or sectors as SETUP is different than the ACTUAL disk size, you will want to
- make the DOS partition very small to minimize the wasted space.
- #-----------------------------------------------------------------------
- # HELP FOR THE PARTITIONING MENU
- #MSG09
- NEW PARTITION TABLE is used to create the table itself. This must be performed
- at least once on a new installation. If you wish, you will be able to assign
- partitions on a MEGABYTE basis, and/or you can use the following options to
- further customize the table.
-
- ALLOCATE will create a new partition assignment.
- DELETE will delete any partition assignment.
- SELECT will cause any partition (1-4) to be selected for subsequent boot-up.
- CHANGE is generally used to change partitions from WRITE-READ to READ-ONLY
- status.
- #-----------------------------------------------------------------------
- # CONFIRMATION OF WRITING CONFIGURATION INFO TO THE DISK
- #MSG10
- If you change miscellaneous parameters, add a disk drive, or otherwise
- alter the disk subsystem configuration, you must WRITE the new configuration
- information to the disk. The new configuration will then be recognized by
- DISK MANAGER on subsequent re-boots.
-
- If this is a new installation, please remember that the configuration
- information cannot be written to the disk by DISK MANAGER until the disk
- is initialized. Further, remember that the configuration information is
- automatically written by DISK MANAGER any time an initialization is
- performed on cylinder 0, head 0.
- #-----------------------------------------------------------------------
- # HELP FOR THE CONFIGURATION MENU
- #MSG11
-
- The Configuration Menu is used to help you identify the actual disk parameter
- information to ensure that DISK MANAGER installs your disk correctly. Your
- configuration is STANDARD if all disks have parameters that are correctly
- displayed on the upper half of the configuration screen. If you have any
- disks which have other parameters, you will need to either re-configure the
- switches on your controller card (XT), re-run the computer SETUP process (AT),
- or use the NONSTANDARD option of this menu to allow DISK MANAGER to
- correctly utilize your hard disk(s).
- #-----------------------------------------------------------------------
- # ENTER MODEL-CODE FOR YOUR DISK DRIVE
- #MSG12
- DISK MANAGER-SEAGATE provides CONFIGURATION DATA for many SEAGATE
- hard disks. The mechanism below should be used to inform DISK MANAGER
- what type of hard disk(s) you are using.
-
- If your disk drive is in fact a STANDARD disk (one that is DIRECTLY supported
- by the BIOS of your particular computer) then you may inform DISK MANAGER that
- the drive in question is STANDARD by just striking "ESC". If your
- disk drive is a SEAGATE hard disk from the table below, use the arrow
- keys to select the appropriate model of your drive, then strike "Return".
- #-----------------------------------------------------------------------
- # DO YOU WISH TO PRESERVE EXISTING PARTITION DATA ?
- #MSG13
-
- You have asked DISK MANAGER to create a NEW PARTITION TABLE in the
- DISK MANAGER format. DISK MANAGER has noticed that you currently DO
- have a valid partition table, and is giving you the option of transferring
- the partition information from that table to the new one about to be created.
- Respond "Yes" to this prompt if you wish to save the existing partition data.
- Respond "No" if you have no need to transfer that data to the new partition
- table.
- #-----------------------------------------------------------------------
- # DO YOU WISH TO WRITE THE ABOVE PARTITION TABLE TO THE DISK?
- #MSG14
- If you are confident that any changes that have been made to the partition
- table are desirable, respond "yes" to this prompt.
-
- If you have altered partition table entries which specified partitions that
- contain any valuable data, that data will be LOST ! If this is the case, you
- should respond "NO" to this prompt, and back-up your valuable data before
- altering the partition table.
-
- THE NEW PARTITION TABLE WILL BECOME EFFECTIVE AFTER
- YOU WRITE IT TO THE DISK AND THEN RE-BOOT YOUR SYSTEM.
- #-----------------------------------------------------------------------
- # SPECIFYING INTERLEAVE DURING INITIALIZATION
- #MSG15
- INTERLEAVE is a term which refers to the ORDER in which physical sectors on
- the disk are used. Generally, the DISK MANAGER default value takes into
- consideration the controller-type and the computer-type being used. Therefore,
- most applications should use this. If you have unique hardware or software
- considerations, and have insight into an INTERLEAVE value which may give better
- performance, you may enter the interleave value here.
-
- TERMINOLOGY DIFFERS AMONG THE DISK-DRIVE COMMUNITY. DISK MANAGER USES
- THE INTERLEAVE OF 1 (ONE) TO INDICATE A NONINTERLEAVED FORMAT, INTERLEAVE
- OF 2 (TWO) TO INDICATE EVERY-OTHER-SECTOR, ETC.
- #-----------------------------------------------------------------------
- # ENTER NUMBER OF CYLINDERS FOR A PARTITION
- #MSG16
- The number of cylinders occupied by a partition determines its ultimate
- storage capacity. The bottom line of the screen indicates the number of
- kilobytes (1000 kilobytes = 1 megabyte) each cylinder can store. Remember,
- the DOS format has some associated overhead, so the resulting logical drive
- will have slightly smaller useable data storage space.
-
- The DISK MANAGER default for DOS-type partitions will be about
- 850 kbytes.
-
- The DISK MANAGER default for WRITE-READ/READ-ONLY partitions will be as
- large as possible without exceeding the 33.5 MB limit. To produce a partition
- which is as large as possible, just type in a large number, such as 9999.
- #-----------------------------------------------------------------------
- # DO YOU WANT TO PLACE A SYSTEM ON THIS PARTITION?
- #MSG17
-
- You will want to place a system on the partition if you ever expect to boot
- your system from the partition. Therefore, the DOS partition (on the first
- disk if you have two) will generally have a system placed on it. You will be
- asked by DISK MANAGER (at the appropriate time) to put your system diskette
- into the disk drive and continue. DISK MANAGER will then copy the vital
- system files from that diskette to the partition being prepared.
-
- If you don't wish to ever boot from the partition, there is no need to place
- a system on it.
- #-----------------------------------------------------------------------
- # ENTER 1-11 CHARACTER VOLUME LABEL
- #MSG18
-
- A volume label is an optional 11-character "LABEL" that you can specify
- (optionally) for each logical drive. This "LABEL" will appear on directory
- listings of the drive, as well as "CHKDSK" listings, etc. It is strictly a
- convenience feature, but many users find it useful to specify a meaningful
- "LABEL" for each drive.
- #-----------------------------------------------------------------------
- # DO YOU WISH TO PRESERVE EXISTING FLAW-MAP ENTRIES?
- #MSG19
- If you do not "preserve" the existing entries, the DEFECT-LIST will be
- completely cleared prior to performing the SCAN. ONLY unreadable tracks which
- were encountered during the SCAN process will be left in the list when the SCAN
- completes. If the existing DEFECT-LIST was exactly the same when the disk was
- first initialized with DISK MANAGER, all defective tracks should already be
- initialized as defective, and therefore will be detected as defective during
- the execution of SCAN.
- If you have entries in the DEFECT-LIST which are in addition to those used
- to initialize the disk, you may wish to "preserve" them in the list by
- responding "Yes" to this prompt.
- ******* PLEASE NOTE THAT SCAN IS A PASSIVE READ PROCESS, AND THE *******
- ******* DISK MUST BE INITIALIZED BEFORE SCANNING IS MEANINGFUL. *******
- #-----------------------------------------------------------------------
- # SPECIFYING A BOOT PARTITION
- #MSG20
-
- Enter the number of the partition that you wish to have BOOT-up when the
- system boots from hard disk.
- #-----------------------------------------------------------------------
- # SPECIFYING A PARTITION'S TYPE
- #MSG21
- DOS partitions are necessary to boot the operating system. DOS versions
- prior to version 4.00 require that the DOS partition be less than 33.5 MB.
- DOS partitions cannot utilize the extra disk space of NONSTANDARD
- disk drives. NOTE that if you have a NONSTANDARD disk with a head-count
- different from that of the SETUP disk type (see CONFIGURATION MENU), then the
- DOS partition should be as small as possible to minimize wasted disk space.
- WRITE-READ partitions cannot be booted directly, but can use the full
- capacity of NONSTANDARD drives, and can be larger than 33.5 MB in size.
- READ-ONLY partitions are similar to WRITE-READ, but files can NOT be added,
- deleted, or altered from DOS-- they are "WRITE-PROTECTED".
- OTHER partition types can be specified if you know the "SYSTEM-TYPE" value
- for that particular system. Most systems, however, provide their own utility
- program ("FDISK", etc.) for allocating partitions for that system.
- #-----------------------------------------------------------------------
- # CHANGING A PARTITION'S TYPE
- #MSG22
-
- The DISK MANAGER change-type function is generally used to change the
- status of a WRITE-READ partition to READ-ONLY, after the associated logical
- drive has been filled with data files which need to be write-protected.
-
- Also, if it becomes necessary to change a file(s) on a READ-ONLY partition,
- this option will be used to change it back to a WRITE-READ partition.
-
- THE NEW PARTITION STATUS WILL BE IN EFFECT AFTER YOU RE-BOOT.
- #-----------------------------------------------------------------------
- # SPECIFYING THE TYPE OF DISK DRIVE BEING USED
- #MSG23
-
- If this disk drive is a STANDARD disk drive, you may just strike
- "Enter" at this prompt. The system will then use the drive parameters as
- defined by your computer's disk subsystem BIOS.
-
- Alternatively, DISK MANAGER has the capability of dealing with drives
- as specified below, even though your computer's disk subsystem BIOS may not
- normally be able to support them. If you are using one of these "NONSTANDARD"
- drives, use the mechanism below to specify which drive you are using.
- #-----------------------------------------------------------------------
- # DO YOU WISH TO MODIFY THE DRIVE PARAMETERS ?
- #MSG24
-
- If your disk drive is a different model than the options presented to you
- earlier, or if you have a unique hardware requirement, you may modify the
- disk-drive parameter table, below, to reflect your desired changes.
-
- In most cases, however, DISK MANAGER will default all parameters to values
- appropriate for your hardware configuration.
- #-----------------------------------------------------------------------
- # IS THE DISPLAYED CMOS INFORMATION CORRECT?
- #MSG25
- DISK MANAGER has detected a condition where NO hard disks are responding.
- This can be caused by hardware problems (cables, jumpers being defective or
- incorrectly installed), or by incorrect information in the system CMOS
- configuration memory (PC-AT type computers only). If you wish to change the
- CMOS configuration memory, you may respond "Yes" to this prompt and be given
- an opportunity to reconfigure the CMOS. Otherwise, you may respond "No" to
- terminate DISK MANAGER and determine the reason that NO hard disks are
- responding.
-
- REMEMBER --ONLY DISKS WHICH ARE ATTACHED TO THE TRUE IBM-PC-AT COMPATIBLE
- CONTROLLER CARD SHOULD BE ACCOUNTED FOR IN THE CMOS CONFIGURATION MEMORY.
- #-----------------------------------------------------------------------
- # WHICH DISK DO YOU WANT TO INSTALL?
- #MSG26
- DISK MANAGER has detected the presence of more than 1 physical hard disk
- on this computer system. Please respond with the number of the hard disk drive
- which you wish to run DISK MANAGER on. If you wish to use DISK MANAGER
- to install more than 1 disk drive, you must run DISK MANAGER once on each
- drive.
-
- If you have additional drives which DISK MANAGER does not detect, please
- inspect your cables, jumpers, etc. Also, be sure that your CMOS configuration
- memory correctly describes the number of PC-AT compatible drives attached to
- the native PC-AT controller card (PC-AT type machines only).
- #-----------------------------------------------------------------------
- # CHOOSE ONE OF THE DEFAULT PARTITIONING MODES
- #MSG27
- DISK MANAGER offers 3 automatic partitioning choices, which accommodate
- the many typical installations. If you desire one of these selections, enter
- the appropriate letter (A,B, or C). If you wish, you may CUSTOMIZE the
- partition structure of your disk by picking option "D". If you choose option
- "D", you will be allowed to specify the capacity of each desired partition
- later, during the installation phase.
-
- "PARTITIONS" then become accessible from DOS as unique drive-letters (C:, D:,
- E:, F:, etc.)
- NOTE THAT 1 UNDER 33.5 MB PARTITION IS REQUIRED ON DRIVE 1 FOR BOOT CAPABILITY
- WITH DOS VERSIONS PRIOR TO 4.00
- #-----------------------------------------------------------------------
- # HOW MANY HARD DISKS ARE ATTACHED TO THE AT-COMPATIBLE CARD?
- #MSG28
-
- Respond with the number of PHYSICAL hard disks (0,1,or 2) connected to this
- system's AT- compatible controller card. DO NOT count any hard disks which are
- attached to various other types of controller cards. The information you supply
- here will be used to set the CMOS configuration data within your computer
- system.
-
- REMEMBER --ONLY DISKS WHICH ARE ATTACHED TO THE TRUE IBM-PC-AT COMPATIBLE
- CONTROLLER CARD SHOULD BE ACCOUNTED FOR IN THE CMOS CONFIGURATION MEMORY.
- #-----------------------------------------------------------------------
- # DO YOU WISH TO ENTER THE BAD-TRACK MAP FOR THIS DRIVE?
- #MSG29
- Most disk drives come with a manufacturer-supplied list of defective tracks.
- DISK MANAGER will ensure that these areas are correctly de-allocated if you
- enter them. If not, some of the more severe defective tracks may be detected
- by DISK MANAGER, but the less severe defects may go undetected. Since these
- less severe defects may cause trouble after installation, we recommend that you
- take the time to enter them now. DISK MANAGER also provides a mechanism to
- allow you to (W)rite this defect list on diskette. Therefore, once they are
- entered, if you should ever need to re-create the list to re-install at a later
- date, etc., the tedious task of re-entering them can be avoided by (G)etting
- them off the diskette again. NOTE that the diskette file FLAWX.MAP (X= drive
- number) contains the saved information, and can be edited or printed if needed.
- #-----------------------------------------------------------------------
- # ONLY 1 DRIVE DETECTED, IS THIS CORRECT?
- #MSG30
- If there is currently only 1 hard disk on the system, then you may respond
- "Yes" to this prompt. The drive 1 installation process will then proceed.
-
- If you have more than 1 disk drive on your computer then you should respond
- "No" to this prompt, and determine why DISK MANAGER is only detecting
- 1 drive. DISK MANAGER will assist in making that determination wherever
- possible. If you respond "No", and you are on a PC-AT type computer
- you will proceed to a facility that allows you to manipulate the CMOS
- configuration data kept within your computer.
- #-----------------------------------------------------------------------
- # IS THE SHOWN CMOS DISK DRIVE CONFIGURATION DATA NEED TO BE CHANGED?
- #MSG31
- DISK MANAGER has detected only 1 hard disk which responds. If multiple
- disks are installed but not responding, this can be caused by hardware
- problems (cables, jumpers being defective or incorrectly installed, etc.),
- or by incorrect information in the system CMOS configuration memory. If you
- wish to change the CMOS configuration memory, you may respond "Yes" to this
- prompt and be given an opportunity to reconfigure the CMOS. Otherwise, you may
- respond "No" to terminate DISK MANAGER and determine the reason that other
- hard disks are not responding.
-
- REMEMBER --ONLY DISKS WHICH ARE ATTACHED TO THE TRUE IBM-PC-AT COMPATIBLE
- CONTROLLER CARD SHOULD BE ACCOUNTED FOR IN THE CMOS CONFIGURATION MEMORY.
- #-----------------------------------------------------------------------
- # WARNING EXPLANATION FOR SETUP-TYPE INCONSISTENCY (NON-FATAL)
- #MSG32
- DISK MANAGER has detected a situation in which the drive type (which was
- specified during the computer's SETUP process) is NOT IDEAL for use with the
- specified DISK DRIVE MODEL.
-
- Specifically, there is a type in your system BIOS which is compatible with this
- drive and has a head count which is closer to the drive's actual head count.
-
- If you respond "Yes", DISK MANAGER will automatically re-configure your
- CMOS configuration memory for this other type. You may respond "No" to
- proceed with the installation using the type currently selected.
- #-----------------------------------------------------------------------
- # WARNING EXPLANATION FOR SETUP-TYPE INCONSISTENCY (FATAL)
- #MSG33
- DISK MANAGER has detected a situation in which the drive type (which was
- specified during the computer's SETUP process) is NOT COMPATIBLE with the
- attached drive.
- If you respond "Yes", DISK MANAGER will automatically re-configure your CMOS
- configuration memory for a compatible type, then continue with installation.
- You may respond "No" to abort the installation process. We would then
- recommend re-running the computer's SETUP process to choose a drive type which
- is SMALLER OR EQUAL to the size of your disk in BOTH the head- and cylinder-
- counts. ALSO, if your drive has 9 or more heads, the chosen type must have
- WRITE PRECOMPENSATION turned off, or an "08" for the control byte.
- #-----------------------------------------------------------------------
- # CHOOSING ROOT DIRECTORY SIZES
- #MSG34
- DISK MANAGER allows customization of the size of your ROOT DIRECTORY. This
- size can be designated when preparing the partition, and, once established,
- it cannot be changed without repreparing the partition and destroying all the
- data in that partition. The default value shown in the prompt is that which
- the operating system now in use would have utilized for a partition of this
- size. You may accept that default, or, if you wish, choose an alternate
- root-directory size.
-
- SINCE SOME APPLICATIONS DEPEND UPON GIVEN ROOT-DIR. SIZES, THE USER ASSUMES ALL
- RESPONSIBILITY FOR INCOMPATIBILITY IF VALUES OTHER THAN THE DEFAULT ARE USED.
- #--------------------------------------------------------------------------
- # CHOOSING CLUSTER SIZES
- #MSG35
- DISK MANAGER allows customization of the CLUSTER-SIZE. The CLUSTER-SIZE is
- the fundamental "allocation unit" DOS will use when creating files. ALL FILES
- will consume useable disk space in multiples of this CLUSTER-SIZE. Therefore,
- if you anticipate using SMALL files, the efficiency of disk space utilization
- will generally be better if a smaller CLUSTER-SIZE is chosen. Alternatively,
- larger CLUSTER-SIZES frequently result in better performance for larger files.
- All permissible values are displayed in the table. The default value shown
- in the prompt is that which the operating system now in use would have utilized
- for a partition of this size.
- SINCE SOME APPLICATIONS DEPEND UPON GIVEN CLUSTER-SIZES, THE USER ASSUMES ALL
- RESPONSIBILITY FOR INCOMPATIBILITY IF VALUES OTHER THAN THE DEFAULT ARE USED.
- #-----------------------------------------------------------------------
- # WARNING EXPLANATION FOR SETUP-TYPE INCONSISTENCY (CONFIG MENU)
- #MSG36
- DISK MANAGER has detected a situation in which the drive type (which was
- specified during the computer's SETUP process(AT) or by setting controller card
- switches/straps (XT)) is NOT COMPATIBLE with the attached drive. Generally, a
- situation like this will eventually lead to one or both of the following
- symptoms.
- 1) 1790 DISK ERROR when booting the computer
- 2) An inability to successfully prepare any DOS partitions
-
- We recommend re-running the computer's SETUP process to choose a drive type
- which is SMALLER OR EQUAL to the size of your disk in BOTH the head- and
- cylinder- counts. ALSO, if your disk over 8 heads, the chosen type must have
- WRITE PRECOMPENSATION turned off, or (AT ONLY) an "08" for the control byte.
- #-----------------------------------------------------------------------
- # DO YOU WISH TO START OVER WITH THE ORIGINAL PARTITION TABLE?
- #MSG37
- DISK MANAGER has detected an aspect of the partition table that is not
- legitimate for this operating system. The bottom line on the screen should
- help identify what the problem is.
- You may start over with the partition table you had prior to entering this
- menu by responding "Yes". Or, you may go back to this menu and further modify
- the partition table to alleviate the problem by responding "No".
- Also, the following switches (useable ONLY on the DM command line) may
- be useful in altering DISK MANAGER's partition table legitimacy checks:
-
- /z -- Allows consistency with ZENITH MS-DOS partitioning rules.
- /w -- Allows consistency with WYSE-DOS partitioning rules.
- #-----------------------------------------------------------------------
- # WE HAVE A SWITCH-PROBLEM ON OUR HANDS
- #MSG38
- DISK MANAGER has detected a condition where BOTH of your disk drives are
- configured to be the same drive-type. Since you specified that they are to be
- configured as having DISSIMILAR drive-parameters, DISK MANAGER is unable to
- cause the controller card to correctly support both drives. The condition can
- be cured by re-strapping the controller card such that DIFFERENT entries are
- selected for each of the two drives. DISK MANAGER will then be able to
- correctly install either or both of them as NONSTANDARD drives and correctly
- cause the controller card to recognize their respective drive-parameters.
- #-----------------------------------------------------------------------
- # DO YOU WISH TO PERFORM THE INITIALIZATION?
- #MSG39
- INITIALIZATION must be performed on ALL drives before they become useable to
- store data. This process will be performed by DISK MANAGER, if you respond
- with a "Yes" to this prompt.
-
- Some hardware configurations can take better advantage of a controller's
- ability to transparently manage defects if the INITIALIZATION is performed with
- the controller-supplied utilities for this purpose. If you have such a
- configuration and have taken advantage of those features, you will want to
- respond "No" to this prompt.
- #-----------------------------------------------------------------------
- # What is a CYLINDER SKEW FACTOR?
- #MSG40
- When data is being read off the disk, a certain amount of time is needed when
- switching to the next cylinder. During the time the drive needs to switch to the
- next cylinder, the sector it's looking for has gone by. To compensate for this,
- Disk Manager will format the next cylinder to start a little later so that
- when the drive heads get to that cylinder, the sector will not have gone by.
-
- If you are not sure what skew factor to enter, use the default or if you have
- the time you can experiment to find the value that gives the best performance.
- Ontrack's tech support cannot determine the proper value for your drive.
- #-----------------------------------------------------------------------
- # What is a HEAD SKEW FACTOR?
- #MSG41
- When data is being read off the disk, a certain amount of time is needed when
- switching heads. During the time the drive needs to switch heads to get to the
- next track, the sector it's looking for has gone by. To compensate for this,
- Disk Manager will format the next track to start a little later so that when
- the drive heads get to that track, the sector will not have gone by.
-
- If you are not sure what skew factor to enter, use the default or if you have
- the time you can experiment to find the value that gives the best performance.
- Ontrack's tech support cannot determine the proper value for your drive.
- #-----------------------------------------------------------------------
- # What is a BEGINNING-OF-TRACK GAP (BOT)
- #MSG42
-
- The first physical sector on any given track will start a certain distance
- after the index mark on that track. This distance is referred to as the
- BEGINNING-OF-TRACK GAP (BOT) and is required to allow for head settling
- and general overhead involved with getting the drive ready to read data from
- the media. The manufacturer should be able to give you this information.
-
- If you are not sure what this value should be, you should use the default.
- Ontrack's tech support cannot determine the proper value for the drive.
- #-----------------------------------------------------------------------
- # What is the TOTAL PHYSICAL SECTOR SIZE?
- #MSG43
- The total physical size of each sector on the disk is made up of two parts:
- 1) 512 bytes for data. (Typical)
- 2) An additional number of bytes referred to as Inter-Sector-Gap (ISG).
-
- An example of some of the items grouped into the ISG are PLO Sync, Address
- Field, Address Check, Write Splice, Data Check, Data Pad, ECC Bytes, etc.
- The manufacturer will be able to supply you with this information if you
- not find it in the documentation that came with the drive.
- If you don't know the physical sector size, you should use the default.
- Ontrack's technical support will not be able to tell you what the physical
- sector size is for your drive.
- #-----------------------------------------------------------------------
- # What is the MAXIMUM DEFECT LENGTH?
- #MSG44
- The defects on a hard drive will vary in size according to how many data bits
- are defective. The defect list for your drive may list the length of each
- defect. Search through your defect list and find the defect that has the
- maximum length. Type this number in at the prompt.
-
- If your defect list doesn't give you this information, you may accept the
- default value.
- #-----------------------------------------------------------------------
- # What is the +-% VARIANCE IN SPINDLE SPEED?
- #MSG45
- When Disk Manager determines where the defects are, it will depend on the
- speed of the disk both at the time the defect was discovered at the factory, and
- when Disk Manager is installing the drive. The reason for this is that the
- BYTES FROM INDEX is derived by the amount of time that has passed since the
- index mark was detected. When the spindle speed varies, so does the physical
- distance between the index and the defect. To effectively lock out the defect,
- Disk Manager has to de-allocate an area on either side of the defect to
- compensate for the spindle speed variation allowed by the manufacturer's
- specifications.
