A friend of mine called me yesterday in a panic. He had bought a copy of Windows 7 and in his haste to install it he had forgotten to ensure that all his important files were backed up. Now Windows 7 was running but the data file for his logging program containing details of all his contacts over several years had gone!
I pointed him towards Tech-Pro.net's article on how to recover deleted files. I had an email this morning to say that a trial version of Uneraser had found the missing log file apparently intact. Huge sighs of relief all round! When a file has been deleted, good recovery software will usually restore it, but when a new operating system has been installed on the hard drive a lot of data will have been irretrievably overwritten and all bets are off.
