Hi,
Download Recover My Files from
Data Recovery Software to Undelete Files; Disk recovery; Recover Deleted Files.
Run the program and close the wizard. Then click on the OPTIONS button and in the SEARCH tab change the "Type of file system to search for" to "FAT" only. Click OK, then START SEARCH, then run a Complete Format Recover on the physical drive searching ONLY for .doc, .xls, .jpeg, .wav, .zip, pdf. This should find the FAT table for your and reconstruct all files and display them in Folder View at the end of the search.
The problem you may have, is that because it is such a large disk it will take a long time to find the FAT.
You may like to try shortening the search by first clicking on the OPTIONS > ADVANCED and using the "prompt for start cluster" option to start the search further down the disk past the NTFS partition.
Good luck.
