Seagate sells the "Go-flex" @2TB for $149.99 ($99.00 with COSTCO)
Anyway and i know your'e going to laugh because i did, I bought this thing so it would save me in case it (my 250GB) died.
CDR Taco, My HD (250GB) croaked 1 week after i plugged the thing in. So i replaced it with a 500GB thinking that the replica software was going to work and whoa! The replica drive died too and it was a 2TB replacement drive.
They (Seagate) told me they would replace the unit but if i wanted DATA recovery from the drive it would cost me $700.00-2400.00.
I'm in the middle of re-building my machine and am a bit pissed since i have the original drive and 5 years of stuff i just can't get back.
