Hi ohstop.

EDITED: Here’s a better post from WD Support with a couple of things to try:

URGENT: Just in case you are not aware: reformatting your drive will erase all data. So, if you have data on your 6TB My Book back it up first. Also, if you’re using that drive across Mac and Windows systems, keep the exFAT format. If you’re using it only on Windows, you can reformat to NTFS.
