I have a 3 month old PR4100 NAS with four 4TB drives in RAID 10.
Yesterday, accessing data on the drive became unresponsive - sometimes I could access the data, and the next moment I would be unable. I logged into the NAS control panel and ran a quick system test and the result was a “drive SMART failure”. After running the test all four drive lights turned solid red.
I called WD support and was quickly told that they would replace my whole unit. No troubleshooting. I asked about the data, and they said I’d have to go through a data recovery service first.
The weird part is that ever since that moment where I was having trouble accessing some files, and the drive lights turned red, I’ve been able to fully access the drive - reading and writing. I ran a full current back up of the NAS to a USB drive and all the data seems to be fine. Other than the red lights, the NAS seems fully operational at this time.
The support guy was unable to provide any insight as to what’s happening to this NAS so I thought I’d ask here. Needless to say, this is very disturbing as I bought this 4 bay NAS for the data security only to have the whole unit go belly up in 3 months.
Ideas?
