- DISK MANAGER DIAGNOSTICS OPERATING INSTRUCTIONS
-
-
- DISK MANAGER DIAGNOSTICS is a software utility that provides you with a
- comprehensive test for your hard drive subsystem. DISK MANAGER DIAGNOSTICS
- will operate on any IBM PC, XT, AT or compatible computer system. This
- utility performs exhaustive disk controller tests, disk drive tests, and
- provides clear error detection, error isolation, and corrective action
- information.
-
- Use DISK MANAGER DIAGNOSTICS prior to disk software installation to verify
- your disk controller settings, disk cable orientation, and disk drive
- communications.
-
- Use DISK MANAGER DIAGNOSTICS to maintain your disk subsystem and to
- identify and correct any related error conditions. With DISK MANAGER
- DIAGNOSTICS, you have the capability to scan your disk(s) to identify any
- flaws that have occurred on the disk surface after initial installation has
- occurred.
-
-
- - WARNING -
-
- DISK MANAGER DIAGNOSTICS does have the ability to perform initialization
- and write functions on your hard disk. DISK MANAGER DIAGNOSTICS makes every
- effort to ensure that these operations occur ONLY on the Customer Engineer
- (C.E.) cylinder, which is not normally used to store data. However, since
- the intent of a diagnostic is usually to operate on a machine suspected of
- having a malfunction, it is always advisable to BACK-UP ANY VALUABLE DATA
- prior to running any of the write tests.
-
-
-
- STEP 1: LOAD THE PROGRAM
-
- Boot your computer system from the hard disk if possible, then
- proceed to the DOS "A>" prompt. If you are unable to boot from
- the hard disk, boot from the floppy disk drive.
-
- To invoke DISK MANAGER DIAGNOSTICS, type:
-
- A>DIAG <ENTER> for monochrome display, or
-
- A>DIAG/C <ENTER> for color display
-
- If you are using this utility on an AT&T 6300 PLUS computer or
- are using an XT disk controller in an AT computer, use the
- following command line to invoke the diagnostic:
-
- A>DIAG/P <ENTER>
-
- STEP 2: SELECT THE DRIVE TO BE TESTED (1 OR 2)
-
-
-
-

-
-
-
-
-
-
-
- STEP 3: IDENTIFY THE DISK DRIVE TYPE / CONFIGURATION
-
- The drive parameters are read according to either the operating
- system (DOS), the presence of a device driver (such as DISK
- MANAGER), or the presence of a drive table mechanism.
-
- If your disk documentation agrees with the parameters
- displayed, your disk is considered "STANDARD." If your disk
- parameters do not match those displayed, enter the appropriate
- model code for your disk.
-
-
- STEP 4: THE MAIN MENU
-
- The entire diagnostic is executed via the function keys. The function
- keys active in the MAIN MENU are described below:
-
- F1. RUN ALL TESTS
- F2. RUN INDIVIDUAL TESTS
- F3. REPEAT THE TESTS
- F4. ALLOW C.E. CYLINDER WRITES
- F5. STOP ON ERROR
- F6. SELECT DRIVE TWO
- F7. FORMAT C.E. CYLINDER
- F8. DISPLAY ALL DISK PARAMETERS
- F9. COLOR ON/OFF
-
-
- F1 - RUN ALL TESTS
-
- This option will execute all the tests in the Test Menu in the
- order shown.
-
- F2 - RUN INDIVIDUAL TESTS
-
- This option lets you select and execute one test from the Test
- Menu.
-
- F3 - REPEAT THE TESTS
-
- This option lets you loop on an individual test, or on multiple
- tests. Use this option to help detect intermittent failures.
- To loop on an individual test, select F3 and then F2. You will
- then select the specific test from the Test Menu. To loop on all
- tests, select F3 and then F1.
-
- F4 - ALLOW C.E. CYLINDER WRITES
-
- This option will permit the diagnostic to actually write to the
- disk. The Customer Engineer (C.E.) cylinder is a reserved cylinder
- that is not normally used by DOS. Use this option to verify
- write/read capability prior to initial disk installation, or to test
- the write/read capability of the disk subsystem of an existing
- installation.
-
- WARNING! DISK INSTALLATIONS THAT USE A "DRIVE-SPLIT" MECHANISM
- SHOULD NEVER USE THIS FUNCTION, BECAUSE A C.E. CYLINDER WRITE
- TO THE FIRST LOGICAL DRIVE WILL WRITE TO THE SECOND LOGICAL
- DRIVE RATHER THAN THE ACTUAL C.E. CYLINDER.
-
- PAGE 3
-
-
-
-
-
- F5 - STOP ON ERROR
-
- Select this option to halt the diagnostic on any error. This option
- should be selected when looping on tests (F3).
-
-
- F6 - SELECT DRIVE TWO
-
- In a multiple hard disk drive subsystem, use this option to select
- the alternate drive to be tested. If drive 2 is selected, this
- function key will let you re-select drive 1.
-
- F7 - FORMAT C.E. CYLINDER
-
- This option will permit the diagnostic to actually format one disk
- cylinder. The Customer Engineer (C.E.) cylinder is a reserved
- cylinder that is not normally used by DOS. Use this option to verify
- formatting capability prior to initial disk installation, or to test
- the write/read capability of the disk subsystem in an existing
- installation.
-
- WARNING! DISK INSTALLATIONS THAT USE A "DRIVE-SPLIT" MECHANISM
- SHOULD NEVER USE THIS FUNCTION, BECAUSE A C.E. CYLINDER WRITE
- TO THE FIRST LOGICAL DRIVE WILL WRITE TO THE SECOND LOGICAL
- DRIVE RATHER THAN THE ACTUAL C.E. CYLINDER.
-
- CAUTION: THIS OPTION SHOULD ONLY BE SELECTED IF YOU SUSPECT A
- WRITE FAILURE IN THE SUBSYSTEM.
-
-
- F8 - DISPLAY ALL DISK PARAMETERS
-
- This option will display the active disk drive parameters. If you
- are experiencing difficulty in executing the diagnostic, use this
- option to check your disk configuration file. If changes are
- necessary, change the appropriate parameters using the screen
- prompts, or select a new configuration file as described in
- Step 2 of this section.
-
- F9 - COLOR ON/OFF
-
- Use this option to select either monochrome or color displays.

- STEP 5: THE TEST MENU
-
- The function keys active in the TEST MENU are described below:
-
- F1. CONTROLLER TESTS
- F2. SEEK TESTS
- F3. RANDOM READ TESTS
- F4. READ/WRITE TESTS
- F5. ECC READ/WRITE TESTS
- F6. VERIFY DISK MEDIA
- F7. RETURN TO MAIN MENU
-
-
- F1 - CONTROLLER TESTS
-
- This option performs an exhaustive test of the hard disk controller
- card. This test may be performed with the disk drive either connected
- or disconnected. Fault isolation is to the controller card as a unit.
-
- F2 - SEEK TESTS
-
- This option performs in-out, harmonic and random seek tests on the
- disk drive. Fault isolation is to the suspect device.
-
- F3 - RANDOM READ TESTS
-
- This option performs a random read of the disk to test the overall
- health of the disk subsystem.
-
- F4 - READ/WRITE TESTS
-
- This option performs write, read and compare operations on the C.E.
- cylinder of the disk. The C.E. cylinder must be formatted prior to
- executing this test. Fault isolation is to the suspect device.
-
- CAUTION: THIS OPTION SHOULD ONLY BE SELECTED IF YOU SUSPECT A
- WRITE FAILURE IN THE SUBSYSTEM.
-
- F5 - ECC READ/WRITE TESTS
-
- Error Correction Code (ECC) tests force data errors on the C.E.
- cylinder of the disk, and test the controller's error detection
- (correction) capability. The C.E. cylinder must be formatted prior
- to executing this test. (Main Menu options F4 and then F7 must be
- selected). Fault isolation is to the suspect device.
-
- CAUTION: THIS OPTION SHOULD ONLY BE SELECTED IF YOU SUSPECT A
- WRITE FAILURE IN THE SUBSYSTEM.

-
- F6 - VERIFY DISK MEDIA
-
- This option lets you scan the disk for media defects. This test
- executes a non-destructive scan, in that it does not write to the
- disk surface. Upon completion of the scan activity, you will have
- the option of examining the list of defects found. If new defects
- are detected, use DISK MANAGER to deallocate them.
-
- NOTE: THIS TEST OPTION IS NOT EXECUTED WHEN F1 (RUNNING ALL TESTS)
- IS SELECTED FROM THE MAIN MENU. SELECT THIS OPTION SEPARATELY.
- YOU CANNOT SCAN A DISK SURFACE THAT IS NOT INITIALIZED.
-
- F7 - RETURN TO MAIN MENU
-
- From the Main Menu, additional options can be selected, or the
- diagnostic can be terminated.

- ERROR DETECTION AND OPERATOR ACTIONS
-
-
- CAUTION: ALWAYS POWER-OFF THE COMPUTER AND ANY EXTERNAL POWER SUPPLIES
- BEFORE WORKING ON THE DISK SUBSYSTEM. FAILURE TO DO SO MAY RESULT IN
- PERSONAL INJURY AND/OR DAMAGE TO THE DISK SUBSYSTEM!
-
- When the diagnostic detects an error within the disk subsystem, an
- appropriate message is displayed. By depressing the F10 key, a more
- descriptive error message is displayed, providing the recommended
- corrective action.
-
- In some cases, fault isolation to the specific device (controller,
- command cable, data cable, or drive), cannot be accurately defined.
- For example, a faulty data cable can cause one to suspect the controller
- and/or the drive to be defective. The diagnostic will identify the
- recommended order of investigation in such cases.
-
- Occasionally, the disk subsystem will fail to operate through no fault
- of its own. The following shows some system-level failures that, when
- resolved, could restore the disk subsystem to operation:
-
-
- Problem:
-
- 1. DOS will not boot from hard disk, or
-
- 2. Diagnostic will not load, or
-
- 3. Diagnostics load but will not run
-
-
- Check:
-
- 1. Check proper connection of all external cables (keyboard, monitor,
- disks).
-
- 2. Check proper seating of all card assemblies in the system.
-
- 3. Run system-level diagnostics (normally provided with the computer).
- The system memory test should be executed.

- - NOTICE -
-
- DISK MANAGER DIAGNOSTICS is intended to diagnose any detectable problem
- with your hard disk subsystem. In order to accomplish this, DISK MANAGER
- DIAGNOSTICS uses hard disk functions which are not normally used in the
- course of system operation. These "diagnostic" functions are NOT
- necessarily supported by all computer/controller combinations. Therefore,
- if your system appears to be working without any problems and DISK MANAGER
- DIAGNOSTICS indicates that a diagnostic function is failing, the
- possibility exists that you computer/controller simply does not support the
- diagnostic function itself.
