Sorry, I can't help with recovering your data. I use one of these drives too and it has worked fine for the last couple of years. But I'm a veteran of using disk drives (used to work as an R&D engineer at HP's disk drive division) and the one fundamental rule I learned is: disk drives always fail; you just can't tell when it will be. Thus, I evolved the following strategy for my computer and it has served me well over the years to survive disk drive crashes, both in Linux and Windows. I always have one internal and one external disk drive that are both solely devoted to backing up my data. Since I'm currently using Windows, I keep my data on drive d: and do software installations on drive c:. Drive d: (data) gets backed up every night to both of the backup drives.
In the last 15-20 years, I've gone through 4 or 5 hard disk crashes or events where the computer hardware failed. This backup strategy has saved my bacon every time, so I know it works. Sure, I have to spend a bunch of time installing an OS and all the apps again, but that's just time. Whenever I download some program to install it, the installation executable goes into my /installation directory, which is on the data disk.
Apologies to OP for not helping, but I'm hoping the above information might help someone else. Many folks don't see the wisdom in having a tested backup strategy (i.e., one demonstrated to work) before a catastrophe occurs. Then they get religion quick...
