Hard Drive Locks up 2/3 way through show

[chefdylan]

I have no trouble getting my show started but for some reason 2/3 of the way through the show hoster completely crashes. It sits in cue and then on the top of the hoster window it says that it is not responding and if I shut down hoster and restart it it just says that it doesnt recognize the external hard drive. I have to completely unplug the hard drive and shut down the whole computor. Upon restart, I have to replug in my hard drive....wait a long time for it to be recognized and then restart hoster. Sometimes it is fixed and sometimes not.

I am currently updating all my optional Windows Vista Updates including the "optional software." I am going to also make sure all my sound and graphics drivers are updated...although, I dont think that is related to the problem.

Am I on the right track?
