This started happening to me when I started using samples via Structure and other instruments. I normally use only audio and BFD2 samples on another drive. I realized that I had my audio drives partitioned into two, one for audio and one for samples. (smack my forhead-DUH!) Today I copied all my data to an external, reformatted the drives to one partition so that my samples are on a separate drive from the audio. I also moved the Pro Tools Creative Collection (with Structure, Boom, Mini Grand etc.) off the Applications drive (where they installed themselves by default) and onto the samples drive. So far I haven't gotten the errors again within the time frame I was getting them.

So if you don't hear from me again in this thread it's a done deal. For me it was definitely the cross data accessing between the audio and the samples or the applications and samples on the same drive. I only hope my elation isn't premature.
