CORRUPT DATA ON KINGSTON 4GB

Click start control panel administrive tools computer management disk management right click on your drive select properties click tools you should see click check now click start two boxes automatically fix files and scan for and attempt recovery of bad sectors place then a tick in one box then select check now start or you might tick one box then return after its finished the first repair then return and tick the second box
(I have found better results ticking the first box then reurn and tick the second box) you should not do anything while the chkdsk utility is in progress any input may damage this drive also you might need to do this

hope this helps
