power cable mix up

Specs: Windows 7
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?

Kind Regards

It's extremely unlikely that the mistake corrupted any data on the hard drives.

(edit) Of course the drive electronics could have been damaged.

thanks for the reply, you confirmed what i was hoping.

I decided in the end to remove the casing from the my book and get the hard drive inside (not an easy job). I've most certainly voided the warranty, and to be honest I don't see how I could have avoided it. WD appear to have made it near impossible to remove the casing without damaging it somewhere.

In the end I managed to plug it into my PC via the use of a sata cable and the data is perfectly ok.

I now have £70-80 worth of hard drive, however it is no longer portable, it was worth it though. I would have been charged a fortune for "data recovery"
