RN104 - Western Digital WD4004FZWX Compatibility?
Hello! I have a ReadyNAS model RN104 running with (4) Western Digital Black WD4001FAEX 4GB drives. I'm getting a warning that one of the drives is in danger of failing, so I'm in the process of order...

You should definitely replace the disk.

The current Blacks should be just as compatible as the older generation, so there's no need to seek out obsolete disks.
But you don't need to match the Blacks, you can replace the failing disk with a Red or a Red Pro, and it will work fine. As Sandshark says, there is little performance benefit with the 7200 rpm drives in your NAS. The Reds will perform about the same, and will use less power/run cooler.
Interesting, thank you for the response. I was not responsible for the initial drive purchase for this setup, so this is the first I've looked closely at the different options. Is it safe to assume that the current generation of WD red/black drives will be compatible with my currrent RN104 setup, even if they are not yet listed on the HDD compatibility list? Or should I seek out previous generation drives that are listed?

Hello again everyone! About a week and a half ago, I hot swapped out the failing drive. The system did not seem to automatically start to rebuild the array with the new disc, so I restarted the system. For the next week, the status indicator on the unit said that it was restarting; the logs showed that I initiated the restart, but nothing further beyond routine Antivirus def updates. I assumed it was probably rebuilding the array, so I thought I would let things run their course. A few days ago, I went back into the system admin and tried to shut down to see if that would help move things along or give me any indication of what was happening. I've been met with the same result -- ever since, the unit says it is shutting down, but I'm not seeing any indication that anything is happening in the system logs. There is some disc activity evident, and I can still connect and transfer files.
What are my options at this point? Allow it to keep "shutting down" indefinitely? Pull out the replacement drive and see if that changes things at all? Force a power down and restart the system?
The first thing to do is make sure you have a backup of the data.
Was the disk you inserted blank or was it formatted?
The disk was blank -- fresh out of the packaging. Under Volumes in the system admin, the drive is grayed out in the diagram. It shows a full green bar under X-RAID on the right, with options below for "Format" or "Global spare." On hover in the diagram, the disc state says Unknown. The other three bays are blue, RAID (RAID-5).
I do have a backup of the most essential data, and will see if it will let me run a full former server backup now.
