Hi Mike,
Good to know that you are back up and running. This type of problem can arise if you are playing music while doing the renaming process. One recommendation that we make here in the forum is to only run one task at a time. The albums that you have already ripped should be OK; the previous ripping and compression process is not affected.
I usually do a batch of changes, say 10 - 30 albums, and then run 'Scan Disk' to make sure that the changes are picked up and written into the B2's internal database.
The good thing is that you can run 'Scan Disk' at any time provided you aren't playing music on the B2. What this function does is to read through the B2's 'music' folder from start to finish and rebuild the B2's internal music database.
Something else that we recommend is that regular backups are done to a USB HDD or memory stick using the 'Export' backup function. This gives you protection against any sort of internal disk failure. You will have spent many hours ripping and compresssing CDs and this means that you have invested a lot of time into creating your music collection.
Regards,
Peter.
