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.

16 Hardware Maintenance Manual

Fixed-Disk Tests:

vSeek Tests - checks the physical operation of the drive head.

Linear Seek

Random Seek

Min-Max Seek

Butterfly Seek

vVerify Tests - checks the integrity of the data present on the media.

Linear Verify

Random Verify

vSurface Scan Tests - checks the drive media for defects.

Surface Scan (Linear)

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

Surface Scan (Random)

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

Start SMART Self-Test

Get SMART test results

Other Test Features:

vWrite-Splice Repair - detects and corrects Error Correction Code errors during Verify tests.

vAuto Spin Down - a gradual spin down of the drive platters to avoid damaging the media.

vManufacturer Log - an in-depth manufacturer supported log of errors on the drive.

Multitasking:

To 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 2 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 on a master and slave on the same IDE cable. This generally increases the amount of 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 in 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.

Chapter 4. IBM Enhanced Diagnostics 17

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 as 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:

vQuick Erase Hard Drive

vFull Erase Hard Drive

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

vDestroys the Master Boot Record (MBR) on the hard drive.

vDestroys all copies of the FAT Table on all partitions (both the master and backup).

vDestroys the partition table.

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

18 Hardware Maintenance Manual

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

vPerforms all the steps in Quick Erase.

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

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

vProvides 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.

Chapter 5. IBM Setup Utility program

Attention

A customized setup configuration (other than default settings) might exist on the computer you are servicing. Running the IBM Setup Utility program might alter those settings. Note the current configuration settings and verify that the settings are in place when service is complete.

The IBM Setup Utility program is stored in the electrically erasable programmable read-only memory (EEPROM) of the computer. The IBM Setup Utility program is used to view and change the configuration settings of the computer, regardless of which operating system you are using. However, the operating-system settings might override any similar settings in the IBM Setup Utility program.

This program includes settings for the following:

vSystem Summary

vProduct Data

vDevices and I/O Ports

vStart Options

vDate and Time

vSystem Security

vAdvanced Setup

vPower Management
