Hi Daniel L,
First of all, do you have a full Export backup completed? If not, you should run this function in order to secure your music collection.
It does sound like you have run out of disk space, and that the 'Scan Disk' might not be running properly because of the lack of disk space to operate in. So I think that a careful way forwards would be to do the following.
1. Can you post here the B2 stats for # artists, # albums, # tracks, etc. At the front panel, using the B2 remote control, press the 'Info' button once to get these stats, then press 'Info' button again to get the B2 software version number.
2. Run the full Export.
3. If the Export won't run to completion, then delete three albums, taking a note of the names of those albums, and, for safety, only choose albums that you have the CD for (in case they need to be re-ripped later).
4. Run 'Scan Disk' again and post the results here so that we can provide additional advice.
A full Export of 240GB of music will take about 8.5 hours to complete.
Regards,
Peter.
