I agree it is puzzling and it isn't affecting everyone the same way either. Even with the same models there have been differences reported in the forum. All of my drives that I use are 716s and 760s and I have not had any problems except a noticable slowdown in spinup time. I have noticed that importing is a lot faster after that spinup time. External drives seem to be getting the worst of the problems, but that could be because of USB port speeds contributing to it.

I don't know if this will help, but you could try shutting down, remove the CD drive from the system (unplug cables), restart, logon, give enough time for windows to complete its runup procedures, shutdown, plug in CD drive, restart, logon and let windows reinintiallize drive, Then try Hoster again and see if it made any changes.
