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

“Diagnostics” on page 16.

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

Note: The fans in this system may turn off under normal operation. This is a

noise-level reduction feature, and should not be taken to mean there is something wrong with the system.

download the Diagnostics program, do the following:

http://www.ibm.com/.

Select Support. Select Personal computing from the ″Get product support for″ pull-down menu. Search for the machine type in the ″Quick Path″ box on the left. Select Downloadable files from the options on the left. Select Diagnostics from the pull down menu.

Navigating through the diagnostics programs

Use the cursor movement keys to navigate within the menus.

The Enter key is used to select a menu item. The Esc key is used to back up to the previous menu. For online help select F1.

Running diagnostics tests

There are four ways to run the diagnostic tests.

Using the cursor movement keys, highlight Run Normal Test or Run Quick Test from the Diagnostics menu and then press Enter.

This will automatically run a pre-defined group of tests from each test category. Run Normal Test runs a more extensive set of tests than does Run Quick Test and takes longer to execute.

Press F5 to automatically run all selected tests in all categories. See ″Test Selection″.

From within a test category, press Ctrl-Enter to automatically run only the selected tests in that category. See ″Test Selection″.

Using the cursor movement keys, highlight a single test within a test category, then press Enter. This will run only that test.

Esc at any time to stop the testing process.

Press

Test results, (N/A, PASSED, FAILED, ABORTED), are displayed in the field beside the test description and in the test log. See “Viewing the test log” on page 20.

Test selection

select one or more tests, use the following procedure.

Open the corresponding test category. Using the cursor movement keys, highlight the desired test.

Code

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, serial or parallel port, processor, specific RIMM,

device on the PCI bus.

Date:

Contains the date on which 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 IBM computer. The diagnostic error code is recorded correctly.

Note:

Fixed disk advanced test (FDAT)

PC-Doctor’s (PCDR) Fixed-Disk Advanced Test module (FDAT) is a full-featured highly configurable fixed-disk test suite. The configurable capabilities of FDAT allow users to enable or disable specific tests, enable or disable testing features, control the test log detail, alter testing parameters, etc. FDAT will test for and report most commonly found errors on a fixed-disk drive and is able to test up to 128 SCSI and 4 IDE drives (up to 132 total drives). Drive information is gathered through FDAT’s enumeration of available devices and user specific configuration parameters located in the FDAT.INI. FDAT uses information supplied by these features to indicate specifically what devices are available for test, what tests are available for the device, device properties, etc. Modify the FDAT.INI file in PC Doctor for DOS to change testing parameters

FDAT consists of the following subtests and features.

Fixed-Disk Tests:

Seek Tests: - checks the physical operation of the drive head.

Verify Tests: - checks the integrity of the data present on the media.

Surface Scan Tests: - checks the drive media for defects.

Surface Scan (Linear) Surface Scan (Aggressive) - this is disabled for normal customer use. Surface Scan (Random)

SMART: - checks the SMART functionality for drives that support SMART.

Start SMART Self-Test Get SMART test results

Other Test Features:

Write-Splice Repair - detects and corrects Error Correction Code errors during

Verify tests.

Auto Spin Down - a gradual spin down of the drive platters to avoid damaging

the media.

Manufacturer Log - an in-depth manufacturer supported log of errors on the

drive.

Multitasking:

allow simultaneous testing of multiple hard drives whenever possible, the FDAT module is written as a set of multitasking functions. Each drive under test can run the same test or run a different test at the same time. Each subtest is written to handle a single test pass and all test variables are kept track of in a structure unique for each drive . However, when testing IDE drives, FDAT will not perform simultaneous testing of IDE drives that are attached to the same IDE cable. For example, if FDAT is testing four IDE drives on a PC, it will perform simultaneous testing on drives 1 and 3 first (master drives), then perform tests on

and 4 (slave drives). FDAT will also perform simultaneous testing on a master

and slave that are on separate IDE cables, but will not perform simultaneous tests

master and slave on the same IDE cable. This generally increases the amount

time needed to test multiple IDE drives. Another limitation of FDAT’S multitasking capability is the use of Ultra DMA (UDMA). Only one drive at a time can access the UDMA channel and the UDMA channel buffer must be kept high in order to maintain a speed advantage over other data transfer modes. In order to use the UDMA channel during testing, users must disable the multitasking feature.

Destructive vs non-destructive testing:

Most of the tests found in FDAT are non-destructive. This means that PCDR will preserve any data that is present on the tested media prior to beginning any destructive operations (i.e. write operations). However, users can run certain tests

destructive mode (i.e. surface scan tests). Destructive tests will speed up testing because FDAT does not preserve the data on the media prior to the test beginning. Unlike non-destructive tests, any data present on the media prior to the test beginning is lost. FDAT allows for enabling or disabling destructive tests, as well

specifying a range of destructive and non-destructive sectors on the tested drive. This is done through the configuration of the FDAT.INI .If destructive and

non-destructive ranges somehow overlap, then the overlapped area is considered

non-destructive. For example, if users specify both destructive and non-destructive

ranges as the same, then the entire drive is tested as non-destructive.

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

steps.

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.

Chapter 4. Diagnostics

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

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.
