Like others have said, your disk is dying and is untrustworthy for holding
critical data.
But no one has answered your question yet, so I will :)
I also have a 8gig drive with bad blocks on it. I only use it on a scratch
box for testing -current. I don't trust it at all, and will toss it in the
bin as soon as it plays up again.
After running various formatters and scanners, I identifyied where the bad
sectors were on the disk, around the 6gig mark on mine. The bad section
was about 20-30MB long.
Knowing this, I can now setup partitions around the bad bit. I created a
5.5 gig partition 1, a 1 gig partition 2 (the bad bits), and 1.5 gig
partition 3.
Hope that helps.
