HELP.....Almost saved Seagate Barracuda 2TB.....

[mhcrra1]

Hi All,
New to the forum.....so, long story short, I did something to the power supply of a Barracuda 2TB external drive.....after a lot of research, I was able to buy a used circuit board with the same F/W etc......last night I swapped the ROM chip and VOILA....she spun up and my computer recognized it (in the docking station). At first, it came up just like it always did, I could see all of the folders/files, etc. (even with a little clicking). I was going to try to copy over some files before I junk it because I know it's on borrowed time. I unmounted it from the dock.....looked at another drive, then put it back in and now it is only being recognized as an un-formated drive!!! No more files showing etc. It is at least being recognized.....
WHAT should I do now? I've tried testdisk and it ran all night just coming back with read errors and not a single percentage of completion.
Thoughts? Comments? Suggestions?? Anyone???
Thanks guys and gals!
Rob

Stop using any recovery software like testdisk, you are just killing off your drive. Your only chance is trying to take an image off the drive with ddrescue.

The heads are probably starting to crash...the more you do, the worse it is going to get. Running testdisk overnight was not a good idea. Anyway, I suggest you take it do a data recovery pro.

The data really isn't THAT important to warrant spending money to send it off for recovery....I wanted to try and do what I could myself just for the satisfaction. I will try doing an image with DDRescue and see what that does. Thanks for the ideas everyone.
