Mix-itG
I can tell you that the factory supplied HD is more prone to the vibration problems than some of the other brands. I bought an IBM HD and haven't had any problems with it.
The error that occurs reads; underflow error, HD too slow. Alesis said that it possibly could be a defective drive...., I don't have the problem unless I am in the room with the amp cranked. I like natural power tube distortion thats why the high volume.
Recording right next to a drumkit gave me no problems.
I need to upgrade the software too....I hear that fixes some bugs. I think the latest is 1.04
