- BATES Associates - OPTIM.COM Fixed Disk Setup Utility
-
- Tests conducted prior to the development of OPTIM indicate access speed
- variations of up to 400% on incorrectly formatted fixed disk units! An
- incorrect interleave setting does not prevent the machine from working, it
- only slows down the sequential disk access time.
-
- THIS MEANS THAT YOUR FIXED DISK COULD BE RUNNING AT ONLY A QUARTER OF IT'S
- SPEED CAPABILITY!
-
- OPTIM completes a low level format on the specified fixed disk unit. The
- Interleave setting is timed for maximum efficiency before the format is
- completed. On completion, a partition table is written to the disk which
- allocates the whole disk for MSDOS use. This is the setting required by
- most users, but it can be altered by the FDISK program if needed.
-
- USAGE :-
-
- From the DOS prompt (usually A:> or C:>) type in
-
- OPTIM and hit <ENTER>.
-
- An introduction screen will appear, giving details of program operation.
- When you have read this, press any key, and you will be warned that data on
- the selected drive will be erased by the program.
-
- YOU MUST UNDERSTAND THAT THIS PROGRAM DOES NOT COMPLETE AN ORDINARY FORMAT
- OPERATION. DATA IS COMPLETELY OVERWRITTEN AND CANNOT BE RECOVERED.
-
- Once you have elected to continue, the parameters settings returned from
- the disk controller will be displayed for you to verify. If there are two
- fixed disks on your system, you will be asked to select one of them for
- formatting. If the parameters displayed are incorrect, you should answer
- 'N' and you will be returned to the operating system. Up to this point
- nothing has been changed on your fixed disk. If you accept the parameters
- as correct, OPTIM will begin a test format on a small part of your disk to
- determine which interleave setting is optimum. The results of each test
- will be displayed as they are completed. When all 16 tests are done, OPTIM
- will calculate the best setting and immediately begin to format THE WHOLE
- DISK at that setting. This may take several minutes.
-
- When the formatting process is complete, you will be asked to enter any bad
- track information for the disk. Bad Tracks are areas of the disk which
- cannot be relied upon to accurately maintain data storage. If there are
- any bad tracks for your disk, they will be noted either on a label on the
- disk itself, or in the accompanying documentation. If the details are on
- the disk, they should be noted BEFORE you run OPTIM in order to avoid
- moving the drive unit while it is running. Track numbers should be entered
- as decimal numbers - these may require conversion from the hexadecimal
- numbers that some manufacturers supply. As each track and head location is
- specified, OPTIM will mark that track as bad so that the operating system
- does not attempt to use it. DO NOT RELY UPON THE BAD TRACK SELECTION
- CAPABILITIES OF THE NORMAL FORMAT PROGRAM. BAD TRACKS CAN PRODUCE
- INTERMITTENT ERRORS WHICH AN ORDINARY FORMAT PROGRAM MAY NOT NOTICE.
-
- When you have completed entering these details, OPTIM will write a
- partition table to Track Zero/Head Zero which allocates the whole of the
- disk for MSDOS use. This is done so that you don't need to use the FDISK
- partitioning program. If you require special partitioning, you'll need to
- use FDISK anyway and you should refer to your MSDOS manual for further
- details. Once the partition table has been written, OPTIM will reboot the
- machine to bring the newly set up disk on-line. Ensure that a system disk
- is available in the floppy drive when rebooting takes place.
-
- After the machine has restarted, you will need to format the fixed disk in
- the usual way (see your MSDOS manual) and you may then transfer your data.
-
- OPTIM has been tested on a number of different controller/drive/machine
- combinations without any problems. It is only suitable for the 8 bit bus
- controllers normally fitted to standard IBM PC type machines. OPTIM will
- not work with the 16 bit bus controllers (large slot) used on the AT type
- machines. A later version (OPTIMA) will shortly be available for these
- models.
