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!). -- Konstantin Olchanski Data Acquisition Systems: The Bytes Must Flow!
