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:

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

– Linear Seek – Random Seek – Min-Max Seek – Butterfly Seek

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

– Linear Verify

Chapter 4. Diagnostics 13

– Random Verify

v 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)

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

– Start SMART Self-Test – Get SMART test results

Other Test Features:

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

Verify tests.

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

the media.

v Manufacturer 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. 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.

14 Hardware Maintenance Manual

Installing memory

Type 6826, 8317, 8318, and 8319 computers have two connectors for installing dual inline memory modules (DIMMs) that provide up to a maximum of 2 GB of system memory.

When installing memory, the following rules apply: v Use 2.5 V, 184-pin, double data rate synchronous dynamic random access

memory (DDR SDRAM), non-ECC DIMMs.

v Use 128 MB, 256 MB, 512 MB, or 1 GB DIMMs in any combination.

Note: Only DDR SDRAM DIMMs can be used.

To install DIMMs:

1. Access the system board. See “Accessing system board components and drives”

on page 22.

2. Locate the DIMM connectors. See “Identifying parts on the system board” on

page 23.

3. Open the retaining clips.

4. Make sure the notch in the DIMM aligns with the tab on the connector. Push or

insert the memory module straight down into the connector until the retaining clips close.

5. Slide the CD and diskette drive tray back into position and reconnect any

cables that were disconnected. Insert the holding screw.

Note: Be sure to align the drive tray properly on the drive tray tracks,

otherwise the drive tray will not sit properly, nor will the cover attach properly.

6. Replace the PCI riser and adapters if it was removed.
