	Sounds like the +5V is real close to the lower voltage limit for the
drive. Each time it drops below the minimum that the drive requires, the drive
does a shutdown. Replacing your power supply with something a little beefier
or adding a seperate power supply for the 500XP would be one solution. I've
never been comfortable with powering a HD off the 500's expansion bus..
