I have a DS220+ with 2x 6TB drives in RAID. I used some bad RAM, and now the volume is read-only and won’t restore. I was resigned to backup the data, create a new volume, and restore the data, but I had an idea – will this work?: Basically, I use one of the two drives as its own backup. I pull out one drive and save it, I wipe the other drive and create a new volume, then pop in the drive with files from the old volume, and copy the files over, and then recreate the RAID. Should that work? Any obstacles I should watch for?

One reason I thought of this was that it’s taking forever to manually copy files from the corrupt volume to an external hard drive anyhow, and I trust the external drive less. It’s honestly not even that much data – I can’t imagine internally copying from one drive to another would take longer.
