The date is retrievedfrom CMOS and displayed using the YYYYMMDD format.v ChkDigits:Contains a 2-digit check-digit value to ensure the following:– Diagnostics were run on the specified date.– Diagnostics were run on the specified IBM computer.– The diagnostic error code is recorded correctly.v Text:Description of the error.Note: See “Diagnostic error codes” on page 89 for error code listings.Fixed disk advanced test (FDAT)PC-Doctor’s (PCDR) Fixed-Disk Advanced Test module (FDAT) is a full-featuredhighly configurable fixed-disk test suite. The configurable capabilities of FDATallow 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 andreport most commonly found errors on a fixed-disk drive and is able to test up to128 SCSI and 4 IDE drives (up to 132 total drives). Drive information is gatheredthrough FDAT’s enumeration of available devices and user specific configurationparameters located in the FDAT.INI. FDAT uses information supplied by thesefeatures to indicate specifically what devices are available for test, what tests areavailable for the device, device properties, etc. Modify the FDAT.INI file in PCDoctor for DOS to change testing parametersFDAT consists of the following subtests and features.Fixed-Disk Tests:v Seek Tests: - checks the physical operation of the drive head.– Linear SeekChapter 4.
