Using an old disk for x-RAID
Hi I have a seemingly basic question, but I can't seem to find any answer that covers it completely. I've upgraded my readynas duo v1 from: 1: 500GB disk 2: 1TB disk To: 1: 1TB disk 2: 1T...
Yes.

Is there any difference between hot-adding disks and adding them with the NAS turned off?
Does the RAIDiator perceive it differently?
When you hot-add a disk, the firmware sees the disk-insertion event. That triggers a disk format, and then a rebuild of the RAID array - no matter what was on the disk before.
If you insert a disk with the NAS off, then the NAS looks at the disk contents. If the contents appear compatible, it will simply attempt to mount it (which might or might not work). If it is not compatible, it will generally format and rebuild - though sometimes it will give a "corrupt root" error. If it is unformatted, it will of course rebuild.
So generally, if you are intending the NAS to wipe the drive and merge it with the array, you are better off doing a hot-insert. If that is not your intent, you should of course always power down, and insert.
