I have a Dell Dimension 8100 - Windows XP, with a cd-rom, and a cdrw. When I start the computer up, I get a message saying " Secondary Hard Disk Drive 1 Not Found" "Press f1 to continue, or f2 to enter setup". If I go to setup, both drives show up and are listed as "auto". when I press f1, the boot continues, and xp starts up, with my cdrw not showing up. I then restart the computer, and it loads up again with both drives showing up and working fine. This only happens on computer start up - restarts are fine. I have tried two different cdrws to insure that it is not a problem with the drive itself. Any ideas?
