I ran through Startup Repair a few times, but it hasn't helped. I've tried disconnecting my secondary hard drives and reconnecting them one at a time following restarts. Everything worked fine for a while but, after I tried to burn a DVD, I again got a locked-up computer with only two of the four drives available. Selectively adding the drives hasn't cured things this time, although the C drive continues to work normally.
