so my boyfriend managed to delete a large portion of his data on one of his partitions and i was wondering if anyone knows how to recover deleted data on a fat32 partition (under windows 2000). (he also has an onboard raid controller and has his drives set up with raid 0, i dont know if that is relevant info or not). i havent used windows in over 3 yrs, so i'm at a complete loss as to what to do, so if anyone has any suggestions, i would really appreciate it. thanks!
