if u mean data recovery, try
FileScavenger (paid but u can get a demo version)
*www.quetek.com/prod02.htm?source=google1
make sure u install it it a different partition and if it finds any recovered data, save it in a diff partition until as much data is recoveres as possible....then u can move it back after probably reformatting that drive..
also, do not move, copy, delete anything from that drive rite now. close ne apps wich mite b using that drive.
