My external computer drive keeps going haywire! I'm using Sony Vegas pro 8. I just got a new mac which I'm running virtual windows on so I can keep editing on Sony Vegas. But I'm having a lot of issues. When I try to hook my camera up to capture footage - I get my image on webcam, not the camera I'm using to upload footage and there is this loud wonky sound over the speakers. The most disturbing part is I get a message saying my drive - which is 3 tb external drive - is corrupt and unusable. This has happened a few times and I've have to have someone come in and restore the drive. Sadly some of my folders were lost. What is causing this and what can be done about it? Is Sony Vegas 8 simply not working in virtual windows on the iMac? Thanks for your help!!!
