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.
