Well I tried to do the lead vocal again today. unfortunately I'm having the same problem. My audio is skipping and when I try to record I get a dropout and a message saying that Sonar can't save my recording and that my disk may be full. I know my disk isn't full. As I said before, most of my projects are on an external hard drive and I just cleaned my audio folder on Friday. Before my audio was skipping on the down beet of every 2 bars or so, it's still doing that but now it's also skipping randomly and dropping out randomly as well. Does any one have any suggestions?
