3.3.7.4 Fonnatting a New Fixed Disk Drive
XVME-678/688 Manual
July 1994
Formatting the disk sets bad tracks with a special attribute so other programs (like DOS FORMAT) do
not attempt to use these areas.
After installing a new fixed disk drive, enter the bad track information provided by the manufacturer into
the bad track table. Next, press
<
F7
>
to begin formatting. The following operations are performed:
• Formatting each track of the fixed disk using the current interleave
• Reformatting each bad track as bad so that it cannot be used
3.3.7.5 Fonnatting an Already Fonnatted Disk
If the fixed disk was previously formatted, select
<
F8
>
to begin formatting. The following operations
are performed:
• The drive is scanned for bad tracks, which are added to the bad track table.
• Each track is reformatted using the current interleave.
• Each bad track is reformatted as bad so it cannot be used.
• A surface analysis is performed on the media and any additional bad tracks found are reformatted
as bad and added to the bad track table.
3.3.7.6 Finishing the Fonnatting
The Fixed Disk Format commands perform low-level format operations on the fixed disk drive(s). After
the format is complete, run the DOS FDISK command followed by DOS FORMAT to prepare the media
for use under DOS (or the corresponding utilities for another operating system). Refer to the operating
system manual for more information.
3.3.7.7 Error Codes
When the diagnostics system detects an error, a two-byte hexadecimal code is displayed. The first byte
of this code is the class of error; the second byte is the subclass. The error code class generally
corresponds to a specific hardware system or group of systems. For example, the first class (01) is used
for the system board, so error 0108 indicates a system board error regarding the 8253 counters.
