[Ardour-Users] disk not able to keep up with ardour...

[sara lidgey]

Hi All,

I'm working a a fairly large multitrack production in Ardour and its gotten to the point where I am getting the "The disk on your computer was not able to keep up with Ardour..." message about every 30 seconds while playing back and while recording. 
I'm going to post as much detail as possible below and I would appreciate any advice on solving this problem.  Thanks!
