I read a lot of unclear and unsolved posts about this problem, so here is my take on it in search for a solution:
My Roon Rock installation recognizes the attached optical drive, but refuses to rip cd’s because “Can not rip because all attached storage drives are full”.
Which is not true, there’s a freshly formatted 2TB SSD. The system sees that as well - I actually formatted it from the Roon Rock installation.
Only funny thing here that the drive is listed as a “1TB” but has “2TB available”. I hope that’s a pathway to a solution
So if it’s not in a VM and running on a bare-metal NUC, then try using the Format button again - that size and manufacturer message in your screenshot is completely wrong and utterly bizarre.
If you want to virtualize, consider using the Linux server and use abcde for ripping. This uses the same ripper as ROCK, and there’s a config file that will set everything up so you don’t need to interact, with the CD is ejected once ripped. It uses MusicBrainz metadata, too.
