Error 0x80070570: The file or directory is corrupted and unreadable.
You may have to save any data you need to first, then repartition the drive and reformat it the slow way to see if it has any bad blocks. There are boot disks like UBCD or HiRen that'll help you with that if you don't have a way to run FDisk and if the boot CD doesn't allow you to manuall re-partition and format the drive to kill all that is currently on it. If it formats in seconds, it is fast formatting, if it takes a while, like 10 mins to an hour, that is what we seek, a slow format.
