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
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.
