|I own a WD 'my book' home edition (the one with firewire, usb and eSATA ports). Annoyingly i also own a laptop with a power cable that fits the 'my book' perfectly (i think you can see where this is going).|
The 'my book' power adaptor is rated at 12v, however my laptop power adaptor is rated at 19v. I managed to plug the laptop power adaptor into the 'my book', I realised instantly what i'd done, and yacked it out. I didn't smell any burnt silicon (which i took to be a good sign).
However, when i plug the proper power adaptor in now the led indicator flashes rapidly and the hard disk doesn't spin up at all, it is no longer recognized by my laptop either.
My question is, will the data on the disk platters be damaged? or could it simply be the circuitry in the surrounding case?
