FileSalvage

FileSalvage – Mac software for OS X that will retrieve files that have been deleted (undelete), rescue data from corrupted media, and recover lost files from your hard drive or storage device.

If you lose any files that you want back, just run FileSalvage and if the deleted files have not been written over (of which there are usually good chances), it will recover them. Corruption does not detain FileSalvage. It will process any intact data on the disk and recover whole or partial files wherever they are found.

I want to thank you again for all your emails to me attempting to salvage my files.

I HAVE VERY GOOD NEWS. I discovered today that my files were indeed salvaged by your program.
...

That also allows me to reclaim my auxiliary disk drive by initializing it now.

THANK YOU VERY MUCH.
