- Summary: I need help with a 3rd party disk thats becoming flaky
- Keywords: SCSI disks, bad blocks, surface analysis, formatting

- Dear Colleagues,
-
- My HP 9000/750 with an Instantly Ignited version of HPUX 8.07 doesn't
- seem to let me deal with a 3rd party SCSI2 disc that is starting to
- show bad blocks.
-
- Surely I can map out these bad blocks?! The only tool I have to do
- anything on this sick disc at a low level is mediainit(1m), and
- reformatting the disc doesn't fix or map out these bad blocks.
-
- I vaguely remember that the SunOS format(8) program can extract a
- disc's defect list, add to it and then rewrite it. I'm not sure at
- what level this helps to keep defects out of a filesystem, whether at
- the SCSI disc driver level or at the controler level. I can't find any
- similar functionality under HPUX.
-
- Would anyone know how I can go about fixing this sort of problem?
-
- Any assistance would be greatly appreciated.
-
- Sean Batt
