Very hard, nothing worked anymore.

Uhm...I scandisk'ed it some weeks ago I think, but I'm not using windows
too often. However I once used Partition Magic 3 to decrease my VFat
partition and to make two of it and later on make one big partition out
of those two again, reverting it.

My fstab:
<SNIP>
/dev/hda1 /win vfat defaults 0 0
/dev/hda3 / ext2 defaults 1 1
/dev/hda4 swap swap defaults 0 0
/dev/fd0 /mnt/floppy ext2 noauto 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,ro 0 0
none /proc proc defaults 0 0
<SNAP>

No, I don't use devfs. Oh, of course, having dual cpus, I'm having a
SMP kernel.
