So, I've decided to change both HDD (no RAID) in my MBWE II from 2x1Tb to 2x3Tb (WD Green).
I've read the WD user manual and did as it said (switch MBWE off, open …. etc).
After installing new HDDs into MBWE, upper light started to blink (once in 0.5-1 sec) and lower is constant on.
There's no connection by LAN. WD Discovery said "No network devices were discovered…"
I've tried to RESET it, but got no reaction.
Any suggestions what to do?
