basic question/info--Newbie..

Howdy.. New to the forum.. Been using Pro tools since 6.0 or so.. always LE until I recently upgraded to an HD Native System..



Currently running Protools Version 11.2.1

Mac Mini Intel Core i7

16 GB

Avid HD I/O 16x16



Here's my question that I'm curious to get some info on..



Tracking a band and recording 15 tracks of audio at a time 24-48 with a HW Buffer at 128.. Everything was and still is basically running totally fine.. occasionally I get a AAE error 9093.. 2-3 times through out the 10 hour day.. recording a pretty loud band.. to me, one time is too much..



I adjusted the Disk Cache from normal to 3GB and since then it hasn't really been an issue.. I do notice that on the System Usage Activity monitor the Disk indicator fluctuates wildly and basically goes from 1-2% and will occasionally fly up to 100% and stay there for a few seconds.. This seems to correspond with very loud parts of the tunes where the drummer really lays into the cymbals..

Can someone



1.. explain this?



2.. Can this lead to the AAE error I was getting? Is disk going up to 100% normal?



3.. What can I do to avoid this and any other future issues?



note.. I am using the internal (non-partitioned drive on the Mac) and I did transfer the sessions to an external Lacie drive (5400 rpm thunderbolt that I'm using the USB 3 connector on.. ) I tested with the drummer and the Disk meter did not seem to be as crazy..



OK.. Thanks so much!
