Roon will not recognize my album collection anymore

Is the USB drive formatted as NTFS? If so, then you will need to connect it temporarily to a Windows PC, and then (this is important) safely eject it from the PC. The Nucleus should then be able to read the drive once more.

Can not see USB drive

NTFS file systems don’t like it AT ALL when they are hot-uplugged. That’s why Windows has this: The file system is now probably flagged as unsafely removed and ROCK refuses to mount it: So, attach it to the Windows machine, start a command window as administrator, run chkdsk /f on the disk. Then remove it safely from Windows. Note that Roon does not recommend NTFS for external USB disks connected to ROCK/Nucleus: [image]
