hi all-
preface point #1: i've only run FSCK once, and it corrupted my entire
drive; i lost all data, therefore, i'm not looking forward to running
it again, but ....
preface point #2: this hard drive was in a box whose mobo had to be
replace (>10 capacitors blew)
one of my partitions (/misc; which happens to be an entire hard drive;
i think the drive is western digital) was giving an error about the
/misc partition when i tried to boot the computer and asked to run FSCK
or log in as root to remedy the issue.
to get around this, i logged in as root, commented out the /misc
partition from /etc/fstab, and it started just fine. but after booting,
i tried to uncomment and run 'mount -a', and got these errors:
-- from /var/log/messages (i think that was the log)

can anyone give me any advice on how to repair the disk/partition
without causing (or causing minimal) damage to the drive/partition?
what flags? use a boot disk instead of a booted system? anything else?
thanks,
doug
