I think you are confusing Roon 1148 vs Roon OS 254.
Roon 1148 has nothing to do with NTFS.
Roon OS 254 changed to a much more stable NTFS driver, but it’s pickier about improperly ejected drives (part of the stability effort). I had 2 people having similar issues plug the drive into Windows, run CHKDSK on Windows, and then eject the drive. When they plugged it into a Roon OS machine (1 was ROCK, 1 was Nucleus), it showed up.
I asked your N+ for logs, but I can’t see the exact issue because the drive is disconnected. You are however having some SMB issues with your NAS (it seems to be unreachable from the Nucleus+).
I need you either connect the drive or wait until I have another report of a similar issue that isn’t resolved by chkdsk/eject. Either solution works for me.
Until this drive shows up, or another user has this same issue
