Thanks payman for putting out the error message you got on the fifth screen in Test Disk.
That was indeed a message that I had not anticipated when I wrote that post you had referred.
It would naturally mean that even Test Disk was unable to read your hard disk.
As far as I can see, your hard disk is beyond normal redemption/recovery and may require a professional Recovery if you want to recover any data.
However in all these cases, nothing is definite until proven and I may be wrong too .
Hold on to check whether other experts chipin with their brainwaves.
