I cant access bay four, has the HD controller gone bad?
I have a NV+ RND4000-100NAS (four bay) purchased new in 2011. I only get three lights on the led display 0n the fron of the device during operation, light four is not lit, although all four lights fl...
Hi jxr02
Power Supply Unit. There have been issues with the Power Supply unit but that might just be another issue wherein it is failing to provide power already. Usually the NAS itself won't power on anymore.

The unit is powering on and booting up just fine. The unit just cant see drive bay number 4 (there is no green led lit on the unit for that bay). the drive also shows as "dead" in frontview. I've swapped drives, but that doesnt change anything. Anyone else had this issue?
Hi jxr02
How many drives you already tried inserting? If all of those still show 4th bay as dead then SATA controller might be the issue.
IMO, this would typically happen to an old unit but not all the time. I would purchase a new NAS already or at least another of the same unit.
Hope this helps!

Also try rebooting. In some cases the drivers will disable the port, and when that happens you need to reboot to clear it.
Obviously it would be good to test the original drive. The best way is to test it in a Windows PC (using either SATA or a USB adapter/dock) with vendor tools. That would be Lifeguard for Western Digital, and Seatools for Seagate.
I purchased a used unit (an Ultra-4 in my case) with one bay faluty, and it turned out to be the backplane, not the controller. While parts are not available, you might be able to find a "parts only" NAS with a good backplane. Or it may be time to move on.
The SATA backplane for the NV, NV+, NVX, Ultra4, and Pro4 are all the same, BTW.
