Hi again,
I was able to recover *most* of the test results for my Kingston drive. I've stitched this together from several chunks that were recovered, so bits and pieces are missing throughout, but most of the info is here. Unfortunately, I wasn't able to retrieve the full ouput of the 'flashbench -a' test -- I suppose you can take my word that it has a 4MB erase size until I can run some more tests on this drive :)

Again, if there are more tests you'd like to have done, just let me know and I can run them when I have a chance. I think I've rescued about as much as I can from the drive, so I should have it operational again soon :)
