If You Have a Problem. . .
Eliminate the obvious fault causing problems; i.e., reversed cables, improper drive selection or
termination, etc. This section lists some of the common problems and possible solutions
encountered when installing a drive controller.
PROBLEM:
1790 Disk 0 Error.
CAUSE:
No low level format on hard disk. Wrong drive type selected. Not enough
drive power. Bad cables. Improper drive selection or termination.
PROBLEM:
Drive does not partition.
CAUSE:
Check drive types. Note that drive types for the AT and AT-compatibles
differ.
PROBLEM:
"Error Reading Fixed Disk" appears when booting from hard drive.
CAUSE:
DOS partition not active.
PROBLEM:
Winchester activity LED continuously lit.
CAUSE:
No problem! Drive LED selected for latched mode.
PROBLEM:
For systems with two drives, both Winchester activity LEDs light at the
same time.
CAUSE:
Improper drive selection or termination. Inspect the drive cables. If the
data cables are straight, then set drive C's drive select switches for drive
select 1 and drive D's drive select switches for drive select 2. If the data
cables have a twist, set both drives' select switches for drive select 2.
Consult your drive manuals or dealer for drive switch settings. Finally,
under no circumstance, use twisted floppy cables for the Winchester drive.
Floppy and Winchester drive interface connections differ significantly.
PROBLEM:
Slow and inefficient operation.
CAUSE:
The biggest culprit for this problem is an incorrect interleave factor.
Therefore, some experimentation with the interleave factor may be
necessary. (Refer to the format instructions for setting interleave factor.)
Interleave factors are very dependent on the host operating system and
application.
