Having problems with my HD24 while recording live. I keep getting the buffer overrun error. I used the 80gig drive that Alesis sent with it, and a barracuda 300gig, both with issues, although the 80gig was better. Do you need to run smaller drive's while recording more than 16 or 18 track's? perhaps a lower bit rate?. I went back to using Adat xt's for the time being, but love the convience of the HD24's, and would love to get this to work. Any idea's????
