Data unreadable on 1 TB hard drive


I have a Seagate 1TB external USB 2.0 hard disk which contains 740 GB of data. Everytime I connect, it shows the memory occupied and the remaining memory(190GB)..but when i try to access the folders inside they read empty... nothing is seen in the folders.. I am unable to read any data from it or write to it...

Same is the case with Windows

When I run self-test in Linux ubuntu I get

Reallocated sector count
threshold: 36
Normalized: 61
Worst: 61
value: 6488

Current pending sector count:
threshold: 0
worst: 1

I have very important data in it.. please anyone help regarding this...

What file system is the USB drive using? Is the drive actually mounted on the Ubuntu system? Have you used this drive successfully on this computer in the past? If you can't read in either Windows or Linux, you could have a bad disk. A lot of the normal low-level disk testing routines don't work on USB drives.

If you really need the data, one option is to remove the hard drive itself and try to connect it directly - bypassing the USB interface. But hopefully, someone will have some better suggestions.
