Data corruption is a terrible thing to happen to anyone and there's little you can usually do in the wake of it. However, BadCopy Pro is a damaged floppy disk repair and floppy data recovery tool that can help to salvage some data from corrupted files. It deals with all media including damaged or defective CD data recovery (CD-ROM, CD-R and CD-RW) plus DVD data recovery (DVD-ROM, DVD+R/W and DVD-R/W).
It can also help with annoying burning problems caused by CD-R/W burning problems and retrieval of data from all sessions on multi-session CDs. If you've lost photos on digital camera due to corruption, it can also help scan SD disks for errors and recover data. Finally, it even extends to large external media such as Iomega Zip drives, Jazz drives, MO disks, and USB flash drives.
This program provides no guarantees but it's better than nothing and definitely worth a try if your data has become corrupted.
