Well done!
Paul's advice on how to power off is important.
Also in the good advice set is:
1) do not ask the Brennan to do two things at once - ie if you are ripping do not listen to music at the same time, if you are editing do not play music at the same time.
2) if you have made any changes to the B2's data (music) then run a "Scan Disk" before closing the B2.
3) rip about 20 CDs at a time then leave the B2 to compress overnight.
4) after ripping about 60 CDs, wait for the compression to finish then do a backup ("Export to USB A or C", NOTE this is incremental in operation).
5) before dealing with Playlists make sure you have done a "Scan Disk" first.
