Hello, I have a WD-Sharespace 4Tb box, it was working in raid 5 for years. I decided to replace it with a 12tb unit and use it somewhere else.
I copied all the data over to the new NAS, so NOTHING is on the sharespace, so I have no need to worry about any data on the unit. This unit had the latest firmware installed on it years ago, when it was first installed to the job it was doing.
After I removed all data I ran the factory reset to wipe everything and get it back to out of the box settings.
This is where I start, after about 16hrs I discovered the default volume failed to create, and it tried to setup as a span not raid 5?
So I changed it to raid 5 and let it go thru its paces, again failed.
I pulled all the drives, hooked them one at a time to a PC and used WD DLG for windows to wipe the drives, they all test fine and wipe no problem. Hours later…
Installed them into the Sharespace box, turned it on and waited. Next day it looks ok everything is working , I check, it has a span volume , not what I want… I set the unit to reformat to Raid 5… This time I monitor it much more closely, It finished the rebuild ok at 20hrs or so, then it formats the volume, at the end of the format it has the messege “Failed to make filesystem”
