My Lite-On 48x12x48x (LTR48125W) CDRW will stop working after an extended period of inactivity, like overnight. It does not respond when trying to open normally. I can do a manual eject and load a CD, but it will no read it. The only thing that seems to fix it is to restart the computer, then it comes back to life. I have the latest firmware and have the drive set up as master on the secondary IDE. My Lite-On DVD has no such problems. Any ideas?
