I'm using a new macbook pro running windows vista. Pro Tools 7.4. I'm using a Maxtor 500GB external hard drive to write to. Regardless of what I'm doing, whether it be playback or recording, I get errors either saying to increase or decrease buffer size. I believe they are -6085 and -6088. I've been googling like a mad man, and I can't seem to figure out what the problem is. I'm not very computer savvy, so if anybody could help me out, I'd appreciate it.
