Suddenly, a red led on drive 2:
Volume 1 degraded. Please check status of drive…
Drive failed in bay 2. Replace the failed drive. Contact WD Support.
Drive SMART failure: The drive 2 self-check failed. Contact WD Support.
Raid health: Degraded
Disk health: Bad
HWlib unable to read HD2 temperature
System test: all OK, including drive 2 !!!
Diagnostics screen says: Drive status: Fault
Check disk: no errors
During boot, all leds are flickering blue, ending up in one red led.
I got the feeling that the drive is OK, but the system refuses to use it anymore.
So I bought TB’s of external drives to backup data, took me days.
I almost sent the EX2 back to the vendor, or asking WD for a new disk.
I did a manual rebuild of the RAID
Result: drive 2 is good!
After rebuilding and rebooting: Problem solved
Why is this happening?
Is the EX2 unreliable in itself?
Does it refuse a drive when it is in a bad mood?
Is it a temperature problem? (I saw a maximum of only 52)
I read about fan problems, but this can’t be true, right?
I have used the NAS only a hundred times, and never 24/7.
So what is going on?
