Fixed disk advanced test (FDAT)
PC-Doctor Fixed-Disk
1
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, and so on. FDAT tests for and reports
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, and so
on. To change testing parameters, you modify the FDAT.INI file in PC Doctor for
DOS.
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
