I once saw a similar fault with a SATA disk on a 3ware-SATA controller-
it could not be accessed until power cycled. I assume the disk firmware
crashed (or whatever) and stopped talking on the SATA interface.
Maybe some hot-plug hardware allows cycling power on individual disks
without physically walking/cycling/driving to the computer and doing
it the hard way by pulling the disk out (pulling a spinning disk out, bad,
bad, bad!).
