***DO NOT REFORMAT***
First of all, mount the drive as a slave on the gf's pc and see if it can be mounted and read from
if that doesn't work, call a HD data recovery firm
I fully recommend
www.drivesavers.com
who recovered data from my drive from a laptop that took a dive from a boat into the ocean, bu t I've also heard praises from
www.iomegadatarecovery.com
WHATEVER YOU DO, DO NOTHING UNTIL YOU'VE SPOKEN WITH AN EXPERT IN THE FIELD and by that I mean, anyone who posts in this thread ;)
