General Checkout

This general checkout procedure is for types 2179 and 6643 computers.

Attention:

The drives in the computer you are servicing might have been rearranged or the drive startup sequence changed. Be extremely careful during write operations such as copying, saving or formatting. Data or programs can be overwritten if you select an incorrect drive.

Diagnostic error messages appear when a test program finds a problem with a hardware option. For the test programs to properly determine if a test Passed, Failed

Aborted, the test programs check the error-return code at test completion. See

“IBM PC Enhanced Diagnostics” on page 6.

General error messages appear if a problem or conflict is found by an application program, the operating system, or both. For an explanation of these messages, refer

the information supplied with that software package.

Notes:

Use Beep codes and the IBM Enhanced Diagnostics to diagnose and fix problems.

Types 2179 and 6643 computers default to come up quiet (no beep and no memory count and checkpoint code display) when no errors are detected.

Before replacing any FRUs, ensure that the latest level of BIOS is installed on the system. A down-level BIOS might cause false errors and unnecessary replacement of the system board. For more information on how to determine and obtain the latest level BIOS, see “BIOS levels” on page 71.

Provides messages that warn the user that this is a non-recoverable process.

Full Erase Hard Drive provides a DOS utility that performs the following

The

steps.

Chapter 3. Diagnostics

Performs all the steps in Quick Erase.

Provides a DOS utility that writes random data to all sectors of the hard drive.

Provide an estimate of time to completion along with a visual representation of completion status.

Provides messages that warn the user about non-recoverable process.

Important: Make sure that all data is backed up before using the Quick or Full Erase functions.

select the Quick Erase or Full Erase Hard Drive utility, use the following

procedure.

Select the UTILITY option on the toolbar and press Enter.

Select either the QUICK ERASE or FULL ERASE HARD DISK option and follow the instructions.

Iomega Zip drive test

Use the Iomega Zip Drive Test to test the Zip drive and the drive interface. The test takes about 20 seconds to run.

The default tests the following:

Controller

Max Seek (50 times)

Random Seek (300 sectors)

Notes

The low-level format is not available on all diagnostic diskettes.

Before formatting the hard disk drive, make a backup copy of the files on the drive to be formatted.

Use the Low-Level Format program in the following situations:

When you are installing software that requires a low-level format.

When you get recurring messages from the test programs directing you to run the Low-Level Format program on the hard disk.

Preparing the hard disk drive for use

When the Low-Level Format program is finished, restore to the hard disk all the files that you previously backed up.

Partition the remainder of the hard disk for the operating system. (The commands vary with the operating system. Refer to the operating system manual for instructions.)

Format the hard disk using the operating system. (The commands vary with the operating system. Refer to the operating system manual for instructions.)
