I have a WD My Book 1130 that was working fine. I had it disconnected, and when I tried to plug it in and use it my system hung up. The drivers will not load, the drive doesn’t show up in Disk Management. I have tried everything to get this drive to come on line. The next step is to send it back to WD since it is still under warranty.  But I don’t want to send it back with data on it.  Any suggestions on how I can get this drive to work, or how I can make sure my data isn’t recoverable before I return the drive to WD?
