Please refer to my original question about this issue. I tried GetDataBack and it doesn't seem to scan or do anything. I chose the default settings from the first screen and then on step 1 I chose my HDD that's damaged.

In step 2, nothing happens. It doesn't scan or do anythong, and on step 3 it doesn't display any of my files.

I have also tried TestDisk and what happens in TestDisk is that when I try to fix and rebuild the MFT, it says this:

MFT and MFT mirror are bad. Failed to repair them.

Here is the status of that HDD under Testdrive:

I also tried this app and got no results when I tried to recover the files. I keep getting this error:

Last but not least, I tried Recuva and that simply says it's unable to read the MFT.

Any suggestions? I have tried various apps already and none of them seems to work.
