i'd say ... important lesson ... make backups ..

	a far away colo ... 
	by not allowing reinstalling, it keeps the data intact
	which is a good thing

i assume that you're implying that the disk still spins ...

- move the disk to another pc  or boot off a standalone disk
  and copy data off the "dead" ( but spinning ) disk

- last resort is to take the non-spinning disk to a disk-repair place
  and pay their $100/MB to recover the data of the 10GB disk ( $10K )
  ( one needs nice fancy toys w/ bunny suits to look at the platters )

if moving the disk or booting off something else is not permitted, in the
far away colo, i still think one is s.o.l... for not having backups
