I bought a USB hard-drive, I installed it on my win98se pc (pentium 3 - 120 megs - 256 megs-ram) and when I reboot (with or without the usb harddrive) both my cd-rom and cd-rw disappear and are no longer in the "systems" menu. I got the most recent updates for windows and my device but the cd-roms still dont come up. If possible, could you help me try to troubleshoot it without having to buy a newer version of Windows, since that is out of the question 'cause I'm using my work PC and my boss is unwilling to pay for the updates.
