Hi Joris,

I don't know if the business-card iso will work since I've never used
it.  I'm on dialup and it doesn't have ppp support.  The netinst.iso
isn't that much bigger (it just won't fit on a business card size CD)
and does have rescue mode.  

However, either should be able to give you a shell where you can run
e2fsck -f.  If you really want to exercise the disk, do e2fsck -f -c -c to
do a full read/write test of the filesystem.  This has the advantage of
forcing the drive firmware to remap any bad blocks that have cropped up.
Yes, I know, that should happen transparently all the time, but then
again, shutdown -F should actually force a filesystem check.
