I have a 2 disc Raid 1 system. I know it writes to both HDDs but what disc does it read from? Always 1, always 2 or alternates ? (assuming system knows none of the hdds are bad).
If I suspected some files were corrupted on one HDD, is there a way I can force it to either read from 1 or 2 via the dashboard without taking out HDD 1 or HDD 2 to see results? Can't see any commands in the control panel to force operation from just one disc or the other.
This is a tech question for synology, but I've wondered how it knows a HDD is "bad" Is there some background write, read, erase test program going on with each HDD to determine health? Does it possibly read both discs each time and if not matched, then start looking for problems in one of the disc?
All this stems from a very bad experience I had with a 5 drive Drobo 5N. With all the beyond raid BS they advertise, I had corrupted data (presumably from just one of the disc sets) that it knew nothing about, never flagged warnings, etc. Numerous word documents and pdf files looked "normal" as far as you could see on windows file explorer, but were annunciated by word and adobe as corrupted, unable to open.
