If it's a year old perhaps it's still under warranty? I'll admit, I've never had an external HDD, but with internal computer parts you'd expect a 3-5 year warranty for most things. External HDD's may or may not be the same.
I got it back working, in linux.
formatted and i can put back files on the HDD.
im only not so happy with al the payed and freeware for data recovery, no program helps.
Easeus Data recovery,
somebody else got a bether program ?
