I have mycloud mirror RAID1 with two 6T drives.
My HDD#1 drive failed so i insert a whole new drive to replace. it rebuild automatically but stop at 6%. the new HDD shown degraded!! so i do a quick check the result is ok.
RAID page says degraded but Drive state page say both healthy. (I know many people have this issue!)
and both LED are BLUE.
Now the problem is, I can’t find a button to manual re-build the HDD#1. the below manual rebuild button is not shown.
Now I have shutdown the NAS. what should I do next?
just restart to let it auto-rebuild again? or click change RAID mode?
Will I loss my important data in either way?
Q1. Can I start NAS with HDD#2 ONLY so I can backup my files?
Q2. If I startup with two drives, will NAS get confused which one to be rebuild? i worry it will auto rebuild and do wrong direction. should I format it in Windows first so NAS will know easier HDD#1 is new to be rebuild.
Q3. can i plug good HDD#2 to windows PC to backup?
thanks for your help.
