I have two physical drives that have become crippled. When I look at the 'Device Manager' list I see the two drives with a Red Exclaimation in front of the line items. I right click on each of them to un-install. One is a Toshiba DVD read drive and the other is a Sony CDRW drive. My W2k OS is suppose to find and attache the device driver upon reboot, which it does not. I beleive the cause of this problem was when I loaded a bad version of Nero 5.5 that was expired. When I un-installed it using MS s/w remove tool it left stuff in the registry. I went thru the registry and removed all other 'Nero' related items. My system had Roxio EZ CD creator running on it before, now it says I'm missing some .dll files. They mush have been deleted from Nero removal. How do I restore or re-install the two drives?
