I have WD My Cloud EX2 and two HDD WD red series - 4T.
I had before only empty NAS and one HDD (separately). HDD is crashing in 50% of cases after turning on NAS - HDD’s LED was blinking rapidly red. FW on NAS is 1.05.30.
So after I bought second HDD WD red series - 4T too.
Second HDD is good (only 2 times crashed after started NAS), but If I connect both HDD, never it does not work. - > both HDD’s LEDs blink rapidly red and I cannot connect to admin page… Code: 201
But first HDD seems OK. S.M.A.R.T. data shows me good health of this HDD. So, I formated HDD again and NAS turn to factory settings. But not change… It is very weird.
And one more thing.
after that, I cannot change RAID… I see only JBOD, noting else.
What is wrong and how can I fix it? It is bad disk or NAS?
Btw why WD My Cloud EX2 has a special file system? I cannot read HDD in Windows through my PC - I see RAW file system. Why NAS does not use classic NTFS file system?
