Have been using my 8Tb (set up as a 4Tb raid drive) for about 18 months for backups, photo storage etc without any problems. I bought from Amazon UK in Oct 2014.
I noticed that the top LED is now flashing red and the LED for drive 1 is a a solid red. I’ve switched it off, taken out and re-seated the drives, switched back on and still have the flashing red top LED and solid red for drive 1.
Quick check with WD Data Lifeguard and Win 10 disk check shows no problems, BUT I think the LEDs are trying to tell me that all is or shortly will not be well with drive 1! Any more diagnostics I can do accurately pinpoint the problem?
Also, with the drive only being 18 months old, wondered if there was still any warranty remaining on it. If so who do I contact, Amazon or WD UK?
