I have a mac g5 dual 2.5 ghz with a my book studio edition II 2 tb external. Since I’ve got the drive a week ago I’ve had to replace my power supply and today I woke up with a kernel panic (fans running full blast w/black screen). Now my drive keeps shutting off by itself. The icon just disappears, WD drive manager stops and the drive powers off. I’m not turning it off or ejecting it. I can get it on for a few min by pressing the power button on the back then it just turns off again. Time machine has been backing up every hour up until today, and now it’s only backing up when I manually turn the drive on. Drive manager says temp is ok and drive is healthy. Anyone know what’s causing this? Thanks!
