There are other posts like this that offer us an insight that this feature can be slow and if you let it finish may result in a very long startup time for Sonic.
Forget about it as a feature.
I have the RecordNow that came with my system (Sonic RecordNow ver. 7.0). Before when I had like 20 mp3s on my system it would scan w/o problems and pretty quickly. Now I have tons of mp3s and when I select the "scan for music" option RecordNow will totally freeze up and I'll have to manually shut it down using ctrl/alt/del.
Can anybody tell me why this is happening and if so how do I fix it?
I can still browse and use the drag and drop option, but I cannot scan at all.
