Noticed today as I finished changing the mobo/chipset on my server, that there is a spot to enter drive warranty and purchased date info in SMART attribute area, thought this would be good for ease of record keeping and future reporting. (not sure if this is attached to device, or something handy unRAID has tacked on)
However when it came to unassigned devices, these attributes seem to be shared across all UD devices.
Although not by any means a high priority, it would be nice if this was simple/quick to resolve.
