[SMAUG] Bad HD?

[Raphaël Dorado]

Hello David,

I wonder if you should not send this material to the kernel
mailing list, it seems appropriate.

If I get it right, ide0 usually handles (hda,hdb) and ide1
handles (hdc,hdd) which seems correct (hdc2->ide1).

What I would try to do is to identify which directory
corresponds to entry #113706, duplicate it's content
into another directory and then exchange the names of
the original and new directories. I would not delete
the old directory since it "uses" the possible bad
sector(s) on the HD.

Still, the best solution is probably to backup the hard
drive, make a low level format (with errors detections),
and restore the data onto the repaired disk.

Good luck,

--Raf
