Apropos fsck'ing, always work on a raw device. Only fsck on an unmounted
partition, or a quiescent one (no disk activity, this means single-user mode
and sync BEFORE doing the fsck). If fsck finds an error, DONT sync the system
before shutting down; sync will flush out anything still in the cache, possibly
overwriting the changes fsck made to the disk.

Someone had to point this out to me a few years ago, I kept doing
sync sync sync reboot after fsck reported errors. Deary me!

Cheers all,
