My hard disk partition D gives a problem. It can not be read and pop up the message "the disk is not formatted". I had sent it to computer center to check. The technician said it is confirmed corrupted and nothing he can do.
I wonder it is really nothing can be done before I format it? I have tons of stuff inside. God damn it!
If I format it as per the technician's advice, is it possible to recover the data? I heard some date recovery softwares are available(from huasing), which one is better by your experience? can it be downloaded from internet?
BTW, C drive is still working and that is why I can raise for help.
Many thanks in advance.

I have no idea how to use these programs. Is it run after I format the damaged patition on the working one. I will search them on google.

I use finaldata enterprise version and get back all the things plus some bouns(which I deleted before).
