Thank you! That was the fix I was looking for....

You can remove the phantom drive from the Music > Location node in the Media Tree: https://www.mediamonkey.com/wiki/WebHelp:Library/5.0#Location

It generally occurs when drive or PC are swapped as this changes the driveID on the drive. When this happens, and before scanning files again, you can fix this using manually re-assign drive: https://www.mediamonkey.com/wiki/WebHelp:Adding_Existing_Files_to_the_Library/5.0#Manually_Re-assign_Drive

New user of MM Gold. Scanned big library, and not sure what I did but there's the physical drive "F:\ 1_music" and a phantom drive "F:\ music". The later doesn't exist, but every track show up doubled and f:\music doesn't play.

This is a show stopper.

Please help.
