Roon confused with Windows drive letter on watched folders

[ben (Ben Coburn)]

I’m glad changing the volume ID fixed your problem, always nice to have people working again.

@Andre_Gosselin

But this begs a second question. If the Roon database refers to my media through a unique VolumeID, what will happen if (following a disk crash for ex.) I replace an external disk with a copy holding the same exact directory structure but with a different ID ? Will the database still behave correctly or will it have to be carefully updated using a special procedure ? If the disk used as a replacement had the same Volume ID, I guess Roon would use it without any problem. This is an important issue for me, as my meda library is somewhat extensive (60K tracks, 3K albums).

I would expect that you will just have to edit the watched folders to point to the correct locations on the new drive, but shouldn’t have to do anything else if the directory structure is otherwise identical.

@ben will put me right here but I think it was not Roon that was confused it was Windows.

I’m pretty sure this is a Roon problem, not a Windows one.

Thanks again for your help. Since you say" I would expect you will just have to …", is it because you are not 100% sure and nobody verified that before ?

I would volunteer to test that, provided I have a 100% guarantee that the following procedure will let me restore my Roon system to its exact pre-test state without nothing else to do.

1. Shut down Roon.
2. Sync the external drive holding all my media (let’'s call it “drive-1”) to a second drive (call it “drive-2”), the only difference between the two drives being their respective VolumeID.
3. Take a backup copy of the Windows directory holding the Roon files (for me: C:\Users\User\AppData\Local\Roon).
4. Unplug drive-1 and plug in drive-2.
5. Restart Roon, and update the watched folders locations. Only the drive letter should differ.
6. Test if everything works OK. Otherwise, do the following.
7. Stop Roon.
8. Unplug drive-2 and plug drive-1.
9. Restore the Roon windows directory from the backup taken at step 3.
10. Start Roon.
11. You should be in the exact same state as before step 1, without having anything else to do.

Please indicate if the above is bullet-proof. If so, I will gladly execute this test.
