ACB-232XB User's Manual
If you have entered a defect list, it will be displayed on the screen for you to verify. Note
that the defect locations have been translated into cylinder/physical sector format. Surface
numbers correspond to head numbers. (Choice 4 CYL/HD/LOGICAL sector, only appears
with a previously formatted drive. This allows the user to add "grown" defects at a later
date.)
Step 6: Select Interleave Factor.
Now select an interleave by typing the desired interleave factor (1 to 12) and pressing
return. An interleave factor of one is the default.
Step 7: Allow a Spare Sector for Defects?
For example, if an ESDI format has 36 sectors on a track, this option formats with 35
sectors and uses the 36th sector as a spare. When one sector must be marked bad due to
a surface defect, the spare is used instead. Then the drive appears error-free to the
operating system. However, 1/36th of the drive capacity is not used. Normally, you will
want to take the default [N].
Note: If you select spare-sectoring, you will not be able to use the 17 or 63 sector
translation options.
If you have entered a defect list, it will be displayed on the screen for you to verify. Note
that the defect locations have been translated into cylinder/physical sector format. Surface
numbers correspond to head numbers. (Choice 4, CYL/HD/LOGICAL sector, only appears
with a previously formatted drive. This allows the user to add "grown" defects at a later
date.)
Step 8: Primary Format the Drive, Automatic Data Verification and Automatic Flagging of
Bad Sectors.
Check to be sure that all of the parameters that you have entered are correct, then enter Y
to continue. Enter Y to primary format the drive. The controller will now perform the
primary format. The program formats the drive from high cylinder to low cylinder, marking
the defects as bad sectors. After formatting each track, the program will write and verify
the track with worst case data patterns. Any defective sectors found during this write/verify
process that are not in the defect list will be added to the defect list. The same track is
reformatted with the newly found defective sectors marked bad. The track is then written
and again verified against defects. The process is repeated for every track on the drive.
ECC retries are disabled during this verification.
When the controller has finished formatting the drive, you should see "Primary-Format
complete!" displayed at the bottom of the screen, indicating a successful format. An
example of what you should see on the screen is shown below.
Note: If the format operation does not complete properly, (i.e., Primary-Format complete! is
not displayed after formatting) see Chapter 4, Troubleshooting.
