DISK TESTS
The
Drsk
Tests allow the operator to verify the functions of the Hard Disk Drive Assembly.
Highlight the test by using any joystick to select the option; then press any control panel button to activate.

Disk information
This test routine verifies the interface between the CPU Board Assembly and the Hard Disk Drive itself.
The processor requests disk information. Data cannot be retrieved successfully if there is a problem.
Sequential Disk Read
Thus
routrne tries to access every bit of data in the order it is stored directly on the disk (requires less than 30
seconds). The hard disk drive media may be defective if this routine cannot be completed successfully.
Sequential Cache Read
This routine tries to access every bit of data in the order it is stored in the temporary disk memory cache
(approximately 30 seconds). There may be a fault in the memory circuits if this test is not successful.
Random Disk Read
This routrne tries to access every bit of data in no particular order directly from the
drsk
(requires less than
30 seconds). This test may detect problems with ability to position the drive heads accurately over data.
Random Cache Read
Thus
routine tries to access every bit of data in no particular order from the temporary disk memory cache
(approxrmately 30 seconds). There may be a fault in the memory circuits if this test is not successful.
Data Integrity Test
Thus
test
WIII
analyze the data on the disk drive This endless test determines if corrupted data is on the
disk. Bad data can cause the program to falter even though the hard disk drive is operating correctly.
File System Check
This routine will perform a file-by-file check of the data stored on the hard disk drive.
If errors are detected
the system tries to fix them, then checks the files again. This test takes about 30 seconds (with no errors).
