We've had some problems with our optical disk lately. The disk spins down and then spins up again. Slow things down by quite a bit... Should I get the drive serviced, or is something else wrong?

You have a problem with dust in your OD. We had the same probs here @ Miami. You can find a doc telling you how to strip & clean the OD at j.cc.purdue.edu or I will send it to you. It's not a big deal, but it could be a little nerve wracking if you don't like hardware things. Dave Strout, NeXT Sys. Admin., Miami U. dastrout@miavx1.acs.muohio.edu root@next1.acs.muohio.edu
