iBook G4 ProTools recording problems!!!!!!!!!

Currently i ham having problems recoding through protools on my ibook. I am using an Mbox with 2 microphones which are recording my guitar amp. When reording on protools about 10 seconds into the track i get this message "DAE can't get audio from the drive(s) fast enough. Your drive maybe too slow or fragmented, or a firewore drive could be having trouble due to the extra firewire bandwidth or CPU load (-9073)) I have been into the settings and the DAE playback buffer is set to level 2, H/W buffer size is 1024 and CPU is set to 85%. Can anyone shed any light on this problem as it is doing my head in and i want to get some recording done. Do i need more memory? hard drive?? Cheers, Andy.

Check out the Pro Tools LE Forum for Mbox issues. My guess however is that you are not recording to a dedicated Hard Drive. Its best to have an external FW drive to record to. Mbox itself isnt very stable in itself anyway. Also, try setting your buffers to the highest amout and turn the CPU Load down. Good Luck MT

moving this to the LE forum...

Also, make shure that the energy saver is set to "highest performance".
