NAS device claims drive in a RAID is degraded but S.M.A.R.T. says it is fine
- by Nathan Villaescusa
I have a Synology DS213 with two 600GB drives in RAID 1.
Last night the device reported that my second drive had become degraded and that I should replace it. When I ran a extensive S.M.A.R.T. test the results said that the drive is okay.
How can I confirm that the drive is actually bad? Is there any case that the degraded drive is the good one and that it is actually the other drive that is bad?
