1. Open the corresponding test category. 2. Using the cursor movement keys, highlight the desired test. 3. Press the space bar. A selected test is marked by >>. Pressing the space bar again de-selects a test and removes the >>. 4. Repeat steps 2 and 3 above to select all desired tests. Test results Diagnostics test results produce the following error code format: Function Code Failure Type DeviceID Date ChkDigits Text • Function Code: Represents the feature or function within the PC. • Failure Type: Represents the type of error encountered. • DeviceID: Contains the component's unit-ID which corresponds to either a fixed disk drive, removable media drive, processor, specific RIMM, or a device on the PCI bus. • Date: Contains the date when the diagnostic test was run. The date is retrieved from CMOS and displayed using the YYYYMMDD format. • ChkDigits: Contains a 2-digit check-digit value to ensure the following: - Diagnostics were run on the specified date. - Diagnostics were run on the specified computer. - The diagnostic error code is recorded correctly. • Text: Description of the error. Note: See "Diagnostic error codes" on page 48 for error code listings. Quick and Full erase - hard drive The diagnostics program offers two hard drive format utilities: • Quick Erase Hard Drive • Full Erase Hard Drive The Quick Erase Hard Drive provides a DOS utility that performs the following: • Destroys the Master Boot Record (MBR) on the hard drive. • Destroys all copies of the FAT Table on all partitions (both the master and backup). • Destroys the partition table. • Provides messages that warn the user that this is a non-recoverable process. The Full Erase Hard Drive provides a DOS utility that performs the following: • Performs all the steps in Quick Erase. • Provides a DOS utility that writes random data to all sectors of the hard drive. • Provides an estimate of time to completion along with a visual representation of completion status. • Provides messages that warn the user about non-recoverable process. 40 ThinkCentre Hardware Maintenance Manual

Test results
Diagnostics test results produce the following error code format:
Function Code
Failure Type
DeviceID
Date
ChkDigits
Text
Function Code:
Represents the feature or function within the PC.
Failure Type:
Represents the type of error encountered.
DeviceID:
Contains the component's unit-ID which corresponds to either a fixed disk drive, removable media drive,
processor, specific RIMM, or a device on the PCI bus.
Date:
Contains the date when the diagnostic test was run. The date is retrieved from CMOS and displayed
using the YYYYMMDD format.
ChkDigits:
Contains a 2-digit check-digit value to ensure the following:
Diagnostics were run on the specified date.
Diagnostics were run on the specified computer.
The diagnostic error code is recorded correctly.
Text:
Description of the error.
Note:
See “Diagnostic error codes” on page 48 for error code listings.
Quick and Full erase - hard drive
The diagnostics program offers two hard drive format utilities:
Quick Erase Hard Drive
Full Erase Hard Drive
The Quick Erase Hard Drive provides a DOS utility that performs the following:
Destroys the Master Boot Record (MBR) on the hard drive.
Destroys all copies of the FAT Table on all partitions (both the master and backup).
Destroys the partition table.
Provides messages that warn the user that this is a non-recoverable process.
The Full Erase Hard Drive provides a DOS utility that performs the following:
Performs all the steps in Quick Erase.
Provides a DOS utility that writes random data to all sectors of the hard drive.
Provides an estimate of time to completion along with a visual representation of completion status.
Provides messages that warn the user about non-recoverable process.
