hey there i was happily using an hitachi 40GB 4200 rpm HD in a firewire enclosure, with my powerbook, until today it made a strange noie while working, and since then stopped working. i tried restarting everything, but it doesnt help. the HD just mke strange noises when i switch it on, and will not be even recognized by the computer. i am a musician, and i was storing my projects on this drive so many hours of precious work gone... does anyone know what to do????
