Ouch.
With the larger drives it is a real pain if one dies. Try making an
image of a 250GB drive to play with.
I played with different recovery programs for a 2gig SD card that got
trashed with original photos. It took a lot of time to get the pictures
off of but it was only a minor issue.
Search for other forensic software to try. A few that I have tried
won't write to the same drive that the image file is on. Part of the
"security" features.

Good luck.
