CA50 nailed it. CRC means the drive is physically going out. Back up what you can and format it before trying for a RMA (if formatting is possible. Use a low level format and zero out the drive. The bad sectors should still be visible to the manufacturer.) If it's more than a few years old, bite the bullet and get a new drive.
 
It is not necessarily the drive that is at fault, it may be the computer or the computers USB interface. If possible I would try it on another computer before trying a RMA. Also you could download the manufacturer of your hard drive diagnostic software to check the drive itself.
