hi all, thanks for the help so far! i did everything you all told me to, and guess what, i get the same error. I am running OSX jaguar. 1) i formatted the LaCie d2 80g firewire drive using apple disk utility. i made it into an HFS+. 2) i installed PT 6.01 on my Mac HD 3) In the Window menu I tried to change LaCie 80g from a T to "R" or "P" but it won't allow me...why? "LaCie is not a valid audio playback volume" HELP ME PLEASE! I am about to smash the damn mbox or return it. Thanks abe
