Well, my notebook drive bit the dust. I suppose video encoding, watching a movie, with 96 tabs in firefox and 23 tabs in IE, on a hot summer's night on a black leather seat was too much heat to handle. Lappy froze, BSOD, reboot to "no device found". Removed drive and tried in another machine while holding it -- no vibration or sounds from poweron/spinup.
Does this mean that the failure is likely electrical (on the PCB board)? If it was something with the heads or platters, wouldn't I feel or hear some type of vibration? How can I be sure if it's the PCB board without taking it in to a professional?
I'm thinking that I can switch the PCB board with my brother's identical notebook drive to get my data off.
