Some months ago, I lost (or perhaps Windows lost) about 1.5 GB of data. Actually, the files were still there, but the FAT got hosed. I did not realize it at the time and unfortunately had saved some stuff to the HD. Once I realized what had happened I got a copy of "File Scavenger" - http://www.quetek.com/prod02.htm . I was able to recover most of the files (about 95-97%), although some files were corrupted - mixed content. Fortunately, I had some of that backed up elsewhere - so no data lost. I am not endorsing this particular product, but its out there in case of emergency.
