I'm testing my unattended CD for some time now, and everything is great except one thing: CD/DVD-ROMs stop reading disks. The hardware is OK, disks are readable (computer boots up from CD, but in Windows could not read it). When I'm trying to open the disk it writes "Insert disk...". I tested it on several computers and a lot of them could not read disks (but not all of them). All computers are different, all drives are different, it happens with Winows XP and Server 2003. The only thing that helps is to delete drive from the Device Manager, and after reboot it installs it again and everything is OK (but sometimes only for several days). I could not find anything about this issue on this forum. Is there anybody having the same problem? What causes it?
