harddisk woes after power outage



Hi!

A few days ago, power went out for a couple of hours (no, I´m not 
living in California ;-) ).

After it was restored, the box came back up, but a bunch of files were 
missing in /usr/lib/, so I went to runlevel 1, and re-ran fsck.ext2, 
which found a whole lot of errors and, supposedly, fixed them.

The box seemed to be fine again.

But today my syslog told me:

Jul  1 05:39:22 WatchZwerg kernel: EXT2-fs error
 (device 03:05): ext2_readdir: directory #207768
 contains a hole at offset 5120

(for offsets 1024, 2048, 3072, 4096, 5120, 6144 and 7168).

So, single-user mode and fsck again, which found some 20 duplicate 
blocks, some 50 unallocated inodes, and, supposedly, fixed them.

My questions now are:

- which partition is "device 03:05" referring to (I guess hda5 but I´m 
  not really sure)?
- how can I find out what "directory #207768" is?
- what could be the cause of those errors on a supposedly clean disk 
  (fsck.ext2 -pycfv ran at least 3 times)
- is it high time to start worrying on how to finance a new disk?

The partition layout is:
 /dev/hda2 on / type ext2 (rw,errors=remount-ro)
 /dev/hda1 on /boot type ext2 (rw)
 /dev/hda6 on /var type ext2 (rw)
 /dev/hda7 on /home type ext2 (rw)
 /dev/hda8 on /mp3 type ext2 (rw)
 /dev/hda5 on /usr type ext2 (rw)

Hints, cluons anyone?

cheers,
&rw
