Well I re-added the drive and it marked it as a spare.

Here's the output of mdadm --detail /dev/md0:

/dev/md0:
        Version : 00.90.00
  Creation Time : Sat Mar  1 22:55:38 2003

And here's my /proc/mdstat:

Personalities : [raid1] [raid5]

      60051456 blocks [2/1] [U_]
      [=>...................]  recovery =  6.9% (4162176/60051456)
finish=30.2min speed=30762K/sec

It seems to be rebuilding but will it stay marked as a spare drive or
will it take over the main faulty drive after it's done rebuilding?

Thanks
