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 flash briefly at the initial boot process. I cannot access the disc on bay 4, I have tried replacing with a new drive, but it does not see the new drive either. Has the disc contoller gone bad? has anyone replaced a contoller? This is what I get from the PCI.log below:

Hi jxr02
Welcome to the Community!
While it is possible that the SATA controller is bad or has failed already, there might be a possibility that an issue on Power Supply Unit might be present.
Unfortunately, no spare parts would be available to replace just the SATA controller, you will have to purchase the same unit and transfer your disks. IMO, you will be better off purchasing a newer model NAS like the ReadyNAS OS 6 and migrate your disks through Data Recovery.
NETGEAR Support has that service if you plan on purchasing a new NAS. Here is the page for the OS 6 NAS units.
Hope this helps!

Hi Marc, what does PSU stand for?

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?
