Hi there, my name is***** remember when you read this that I'm just the messenger.
You can't really get them back. You might be able to use a utility to do a low-level search on the disk and try to pick up fragments of data that you could type back into the database to piece them back together. If you want to pursue something like that, let me know.
Also, if I answered your question, could you please accept the answer and rate my service (considering that I'm only the messenger)? Until you accept an answer, I don't get paid anything for helping you. Thanks!
