I have a 2TB hard drive that seems to have died. Really it is "only TV (and
movies)" but if I can get the data back I'd be a lot happier, and so would
la famille.
I have removed it from the backend and attached it to my laptop with a
USB/Sata Bridge (JMicron Technology Corp. / JMicron USA Technology Corp.
JM20337 Hi-Speed USB to SATA & PATA Combo Bridge according lsusb).
dmesg tells me:

gparted and other partition tools claim it has no partition table. I had it
divided into two 1.0T partitions and after a lot of screwing about with
gpart trying to work out where the partition boundaries were I thought I'd
just try and guess and see what I could recover. gparted however seems to
refuse to make a partition table at all.
Is it toast? Can anyone figure out any more steps to try and get the data?
gpart gives no feedback at all, even after running 24hours.
