Default Error Message -9136 and -9094 Buffer size problem?

Hi I have Pro-Tools L.E. 6.4. on a Mac ibook G4, processor 1.33 w/ memory 1.25 ram and 60 GB of hard disc space. The problem I'm having is that when I record or sometimes playback in a session an error message comes up saying that the buffer size needs to increase and when I increase it an error message comes up saying the buffer size to large. My computer is set up to it's highest performance and set to no sleep. I updated the OS to 10.3.7 Keep in mind this happens when I don't have any plug-ins inserted and sometimes with the plug-ins. Can someone please help. It's very annoying when I'm recording and an error message pops up, stopping my session. PLEASE SOMEONE HELP!! I would appreciate it very much.
Later! PEACE!!

Default Re: Error Message -9136 and -9094 Buffer size problem?

I use a powerbook G4 1.33 with PT 6.4 and 002R.
I use to have the same error problem. I know you use a Mbox so some of whats under might not apply but the info is valid nonetheless. Here's what I did after doing some reading in the DUC:

-Disable all options in the energy saver system preferences page. Set processor performance to highest.
-Disable journaling on both internal & external drives using disk utility.
-In your PT preferences under operation, make sure you limit your open ended record allocation to less then 270 minutes. Dont choose : "use all available space". I set mine to 250.

Also, I changed my standard 60G, 4200 rpm internal drive for a Hitachi Travelstar, 60G at 7200 rpm and since then I have no more of these "Could not get Audio From Drive Fast Enough" Error. Internal drives are simply too slow at 4200 rpm.
Dont forget the OS and Protools will read & write faster with a faster internal drive.

Moreover, If you really want to optimize, then use your firewire 400 port for your interface (in the case of a 002
/002R) and get an cardbus to firewire 800 adapter for your external drive. That way both ports will be separated and on different busses. The architecture of the powerbook as both firewire ports on the same bus and ideally you would want to have your processor share the load on two busses, 1 for the interface, the other for your drive.

Btw, I use my internal drive for my audio (I like the portability) on a separate partition that I defrag using Techtool 4 almost after each session and my rig has been great! I mixed a song 2 days ago and this was my tally:

-18 mono tracks
-5 stereo tracks
-16 busses
-36 plugins

Not bad!

Hope this will help,

PS: Thanks to Teleplayer & Jfreak for sharing the knowledge...
