Duo v2 - Can't add second disc
Hi guys. Can someone help? I'm trying to add a second disc to my x-raid volume. This is the second time I've tried. The first was with my original in slot 1. That failed, so I tried turning the NAS...

You had better not use WD Green disk do RAID, because WD officially doesn't support RAID user cases in more than 2-bay device for WD Green disk.***** Disk SMART log for channel 2 [sdb] *****

Hi Evan
OK, sorry for the delay, but I finally did exactly what you wanted.
I used DLDIAG to write zeros (Quick Mode) and then did a quick test. Everything came back OK.
I then HOT inserted into bay 2.
I got the usual notifications in the info centre:

RAID sync finished on volume C. The array is still in degraded mode, however. This can be caused by a disk sync failure or failed disks in a multi-parity disk array.

RAID sync started on volume C.

Data volume will be rebuilt with disk 2.

New disk detected. If multiple disks have been added, they will be processed one at a time. Please do not remove any added disk(s) during this time. [Disk 2]
