Used the wrong power cord - light but no access

Hi all

Last week, in the dark,  I plugged my laptop’s 19v power cable into my  My Book (12v).   Now,  the drive will light up when plugged in, but  won’t be recognised by my computer (and doesn’t make sound).    I’ve had it about three years.

My question is this.  If  I pull the cover off,  does the drive have standard IDE connections which I can use to plug it into another computer and see if the drive itself is still good?

Any other ideas of troubleshooting/fixing this?   Did it likely mess up the power parts or the drive firmware itself?   Much of the stuff on the drive was backed up but some things weren’t any help is apreceiated.



The drive probably has a shorted 12V TVS diode.
