My old drive is full, purchased a newWD250GB Passport drive. I change my backup Config from F drive to the new G drive, when I try to save, it wants to convert backup device to NTFS, I select OK and I get a Conversion failed message and it goes back to the F drive?
Rather than convert, open My Computer, find the new drive, right click the drive and select "format". Select NTFS as the file system. Be aware that formatting the drive will erase any data stored on that drive.
