harddisk corrupt?

[stefan kersten <steve@k-hornz.de>]

hi,

i'm a bit concerned because of the dmesg output i'm getting lately
when accessing certain files (see below). this is on a tibook G4,
debian/unstable 2.6.5 (built from stock kernel sources). any ideas
what might go wrong? i'm still hoping it's not a hardware error ...

thanks,
<sk>

dmesg output:
