Thanks, that clarified things for me.

In fact I had 2 drives failing me nearly the same way, and both where IBM Deskstar for 2000 and 2001. I thought about heat at the time, but was not so sure anymore as they wheren't running so hot. Very sensitive to heat they must be.

Is it possible for a poorly written disk driver/filesystem to trash blocks on a hard disk? By trashing I mean that subsequent access result in an i/o error, aven accross reboot.

I have such a disk where it happened a few years ago. Curiously, the damaged blocks where the first blocks of partitions that where mounted. The maker's test software says the drive's ok, as well as s.m.a.r.t., although it needed a "reformat" with the same tool to get rid of the bad blocks.

I would think it must be some kind of hardware failure, but a recent discussion about linux filesystems makes me wonder... linux was running on that disk, after all, with reaiserfs. And it was 3 years ago.


Ahh... you do know that the IBM DeskStar drives have a huge failure rate. There was a processing error in the manufacture of drives during those years. Major PR problems for IBM, class action suit and they sold the drive division after that.

If you still have data on them that you want to keep
you should copy them else where.
