External HD but after Jan 22, ROCK no longer can see IT

I have an external HD that I was using for backup, but after Jan 22, ROCK no longer can see the drive.

I have checked it on my laptop and there is plenty of space available.

Does anyone have any suggestions?

NTFS formatted?

Yes. It was. I appreciate any advice as I am a technical newbie.

It is better for it to be exFAT, as Linux can have issues with NTFS. Most likely it was unplugged or thebnuc just powered off. This can lead to drive issues. Plug it into a PC and run a check on it.

NTFS disks have proven notoriously problematic with Nucleus/ROCK. Did you update the ROCK prior the January 22?

New updates of ROCK use a stricter driver for NTFS, which is much safer in avoiding corruption. However, to achieve this it refuses to use disks that have any issues in the NTFS format.

If you ever unplugged the disk from the ROCK without shutting it down first, or unplugged it from a Windows PC without clicking the proper “remove safely” button, this would cause the disk to be flagged as “unsafely removed” and then new ROCK versions won’t mount it again to prevent file system damage, until it is checked and cleaned in Windows.

In your case, since it is just a backup disk and doesn’t have loads of music on it, I would just reformat it with the exFAT disk format instead of NTFS. The exFAT format is what Roon recommends for external disks that are attached to ROCK.

In Windows, this is done like this:

Thanks! Reformatted my external drive to exFAT and was able to set my back-ups again. I appreciate all your help.
