How hot are the discs when they come out? I really liked my syjet until I filled up the other bays in my case. Then things didn't work so well, I would start to lose sectors. The drive runs pretty hot, but when I stacked other drives around it, it just couldn't handle it. I haven't as yet had a chance to add a fan to see if that will do enough to fix the problem, but if I only use the syjet for the first few minutes after I start up the machine, I don't have any problems and it indeed works really nicely. --------- Christopher R.
