How is the drive formatted, NTFS?

Hello @Dennis_Beuger ,

Thanks for reaching out. It does look like you have a Nucleus registered to your account, so this may be related to the file format the drive uses. If it is an NTFS drive, you may have not ejected it properly from the previous system. Assuming NTFS:

NTFS file systems don’t like it when they are hot-unplugged. That’s why Windows has this:

The file system is now probably flagged as unsafely removed and ROCK refuses to mount it.

However, once cleaned, Linux should be able to mount it normally..

Recommended Actions:

  1. Connect the Drive to a Windows PC:
  • Run the following in Command Prompt as Administrator:
chkdsk E: /f

Replace E: with the correct drive letter for the USB device.

  1. Safely Eject the Drive from Windows:
  • Always use the “Safely Remove Hardware” option before unplugging it. This helps avoid “dirty” NTFS volumes.
  1. Replug into Linux System:
  • After chkdsk repairs it and it’s clean, try connecting again.
  1. (Optional) Force Mount on Linux (Not Recommended unless necessary):
  • If you can’t access a Windows system:

Additional Information.

Roon does not recommend NTFS for external USB disks connected to ROCK/Nucleus:

Hi @Dennis_Beuger,

The mounting issue in the post above is the single most common cause for the symptom you described.

Are you still encountering this problem after trying a chkdsk?

If so, please share the model of the drive and how you’ve formatted it. Please also try mounting the same drive from another machine.

We’ll watch for your reply. Thank you!

Hi!

It is a LaCie drive. exFAT

Hello @Dennis_Beuger,

Let’s take a quick step back! Your account diagnostics show that there are actually two different Roon Servers associated with your setup recently.

We currently see:

  1. A MacBook Pro (“MBP-van-Dennis”)
  2. Your Nucleus

Interestingly, the diagnostic data shows the LaCie drive was recently registered under the MacBook Pro’s local shares, even though you mentioned it is plugged directly into the Nucleus. This often happens if the Roon Remote app accidentally connected to the Mac instead of the Nucleus, or if the drive was recently moved between the two machines.

To make sure we are troubleshooting the correct device, could you please clarify a couple of details?

  • Which Core are you currently connected to? You can verify this by opening your Roon app and going to Settings > General. Does it say you are connected to the Nucleus or the MacBook Pro?
  • Where is the LaCie drive physically plugged in right now? If your Roon app is connected to the Nucleus, but the LaCie drive was recently unplugged from the Mac without being “Safely Ejected,” the Nucleus will refuse to mount it to protect your data (as mentioned in our previous message). However, if your Roon app is actually connected to the Mac, this is simply a macOS Privacy & Security permission issue.

Could you let us know your current configuration so we can give you the exact steps to fix it?
