How to recover data from corrupted WD external hardisk

[rajmehra300]

Hi...

I have Western Digital Passport 1 TB external Hard disk. It has got corrupted. When I connect to my Window 7 machine, my external hard disk rotates but my machine does not recognize it.I have checked External hard disk with other working cable as well but still it is not working . I have tried to recover data with Hiren boot cd ,. On hiren boot machine it is recognizing the disk. I can copy some data in form of dd format with data rescue but not able to recover data with this DD format file. I have used different softwares to recover dd file but all are giving error. Please suggest how can i recover my data.

Hmm?
dd format?

Do you mean you used dd to read the drive, but, now are stuck with trying to get data from that?

Well, depending on which passport model you are using, you might not ever be able to do that, some have hardware encryption, and well, you can't read the HD except from the original controller.
The dd output file is a RAW format, you need to write that someplace else, or mount it, but, you need to know what you are doing.

In any case, I would clone it to another HD, then work on that one, don't use the original!
Then use testdisk or something along those lines to see if it can find anything.
