h/w buffer size

[padmtkperfk]

I have the same problem. I use the mbox...and I've tried it on the mbox 2. I'm on my macbook pro and I do have 7.1.1. however, the buffer problem doesnt always happen. It's not the hardware cause I've tried two different mboxes so....When I change the buffer setting, it's usually fine. It's just that occassionaly when I move my mouse while recording, the buffer thing comes up. Then there are also the occaionally problem when I bounce. It tells me some long complicated thing about certian lines are missing. This happens after the bounce rendering the whole bouncing useless. I have no clue what it's even talking about with the missing line issue. Usually I just have to restart protools...then it's fine again....occasionally I have to restart my machine...but sometimes, even that doesn't work immediately. It's really annoying. Also, my protools refuses to even read my internal harddrive anymore as a writable audio drive. It happened one time when I ran out of space....But I've moved stuff so now I have space again...but then it still won't let me use my internal drive as a scratch disk. And also...on the side....if anyone has any idea....I have a seagate external drive, 300GB, USB....that only my macbook pro can read. My PC, my brother's PC, and my friend's G5 tower all can't even detect the harddrive. It won't read it at all. It's really strange. I really dont' know what the heck is going on anymore with this whole protools issues. Any help would be greatly appreciated.
