I am having issues when I connect my 3TB MyBook to my 3TB MyCloud. The MyCloud basically freezes up when they are connected. The MyCloud runs fine when the MyBook is removed.
So, WD support has tried a lot of things to get them to play nice and the last thing they asked me to do was a full format (NTSF) on the MyBook to see if something was wrong with the partition or format. I used a Windows 7 laptop to start the formatting (Capacity: 2.72 TB, NTFS, Allocation unit size: 4096 bytes).
The formatting process has been going for about 16 hours now and the drive only shows about 2/3 done. Is this a normal amount of time? I have reformatted 500GB drives and they might take an hour or so but nothing this big.
