Two weeks ago I've purchased a brand new 1TB Hitachi Deskstar 7K1000 in order to use it as an external media and TM backups storage. But both MacAlly G-S350SUA and Thermaltake ST0008 enclosures won't works flawlessly with my drive inside: the disk mounts and works fine until I leave it to itself. Then, whilst trying to copy any file to the disk, Finder will stop and report a '-50 error'. No way to make it back to work or even unmount. If I try to unmount it twice or so, Finder crashes. So, I suppose, the problem lies in the power supply of these enclosures. I'm looking forward to your advice, guys: what external enclosure with FW-800 should I try with my Hitachi drive? What is your experience?
