Hello,
I was running a defragging program yesterday on my 1TB external USB disk and minimized the program. When I wanted to shut down the computer, I put it on Hibernate mode forgetting that I had the defragging program running. Today upon start up of the computer, I did not attach the external drive till it started up. The problem is that the disk is now unreadable! I tried (still trying) various programs to attempt to recover the data but in every program so far, it just shows the size of the whole disk and says that is needs to be formatted. Windows does not see the disk in Windows Explorer. Should I reformat the disk then recover the data? The disk is very full, approximately 700GB of data in it and Recovering all the data would be difficult to sort out! I need to know the best procedure to proceed with. I am running Windows 7.
Thanks! Was this information helpful? | 
I'd like to assist you, can you see the hard drive in disk management?
Did you try to connect the drive to another computer? If not you may try that and see how it goes?
If you don't have any backup, then you can try some data recovery software's online or if the data is really important you can go for professional service which may cost you.
Good luck.
Hope it helps.
