February 24, 20224 yr I have an unRAID server with one 4 TB HDD. There is nothing wrong with it. I don't need that much space so I want to swap it with a 2 TB HDD I have. My thought is to put the 2 TB in an external enclosure, plug it into my unRAID server, do a data transfer, then swap the 4 TB with the 2 TB. But I assume there are some additional steps I gotta do? How do I make sure the data I copied to the 2 TB from the 4 TB isn't lost when I add it to unRAID.
February 24, 20224 yr Community Expert Why not do it he other way around? set up Unraid with the drive(s) you want to keep, and then put the removed drive into the external enclosure to copy its data back to Unraid.

You will have to format the 2TB drive you want in the array before copying data to it, but the 4TB drive you move to the external enclosure can be mounted with no problems. Every array drive in Unraid has a self-contained file system that is readable outside the array. You probably want the Unassigned Devices plugin installed to simplify the mounting of the drive in the USB enclosure.
