Thanks, unfortunately, I don’t know of any tool including DOS that will chkdsk an unallocated drive. It looks like it is just one of the 4 and there is a rebuild feature on the RAID. So I may be able to buy a new disk and let it rebuild.
Do you know how I can chkdsk an unallocated drive? The disk will not be seen in the command prompt or recovery console. Perhaps Western Digital has a tool for this?
Happy Thanksgiving!
