Each time i start up my Xp and look in My computer or Explorer the CDROM and Removable "ZIP" drive assignments fail to appear. I go to ...device Manager and "scan for Hardware changes" and right away it updates and indicated the CDROM and Removable ZIP drive. It assigned the expected drive letters "D" & "E" respectively and evenrything works as it should. But next time I reboot the drives are missing again. I am logged in as Administrator. so what next...
