Well, given the forum you posted in I'll assume you are usig Adobe products for this job.

The last I read, Adobe, simply do not support the use of external or networked hard drives.

The statement does sort of date back to the times when such things were much slower so you shouldn;t really have an issue I would imagine but as you have....

Are things better on an internal drive? try moving yor project to an internal drive and try it again. It might be a sustained data rate type issue.
