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
Chapter 4, “IBM Enhanced Diagnostics,” on page 15.
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.

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.

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.
Chapter 4. IBM Enhanced Diagnostics

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.

Replacing internal drives
This section provides information and instructions for replacing internal drives.
Hard disk drives
drives or DVD drives
Removable media drives
These different drives are also referred to as integrated drive electronics
Note:
(IDE) drives.
Internal drives are installed in bays. In this book, the bays are referred to as bay 1,
bay 2, and so on.
When you install an internal drive, it is important to note what type and size of
drive that you can install in each bay. Also, it is important to correctly connect the
internal drive cables to the installed drive.

Replacing the battery (all machine types)
The computer has a special type of memory that maintains the date, time, and
settings for built-in features, such as parallel-port assignments (configuration). A
battery keeps this information active when you turn off the computer.
The battery normally requires no charging or maintenance throughout its life;
however, no battery lasts forever. If the battery fails, the date, time, and
configuration information (including passwords) are lost. An error message is
displayed when you turn on the computer.
Refer to “Safety notices (multi-lingual translations)” on page 153 for information
about replacing and disposing of the battery.

POST error codes
Each time you power-on the system, it performs a series of tests that check the
operation of the system and some options. This series of tests is called the
Power-On Self-Test, or POST. POST does the following operations.
the POST finishes without detecting any problems, a single beep sounds and the
If
first screen of the operating system or application program appears.
Note:
Some computers default to come up quiet (no beep and no memory count and checkpoint
code display) when no errors are detected by POST.
Checks some basic system-board operations
Checks the memory operation
Starts the video operation
Verifies that the diskette drive is working
Verifies that the hard disk drive is working
enable beep and memory count and checkpoint code display when a successful POST
occurs, do the following:
Select Start Options in the IBM Setup Utility program (see Chapter 5, “IBM Setup
Utility program,” on page 21).
Set Power-On Self-Test to Enhanced.
the POST detects a problem, an error message appears on the screen. A single
problem can cause several error messages to appear. When you correct the cause of
the first error message, the other error messages probably will not appear on the
screen the next time you turn on the system.
