Actually, if you uninstall some cd recording software the CD/DVD drives will vanish. NO DRIVER KNOWN WILL FIX THIS.
Read this fix:
I have a E Machine, 366mz, Windows XP and two Writers
(1) a Sony DVD burner, and a Sony CD-RW writer.
I was working on my computer a month ago, removing some programs thru the control panel and clearing up space on my hard drive. When I went to "my computer"
Neither of my Drives (D: or E:) was there. evidently
I must have removed or deleted a file assosiated with both of the Drives while I was clearing up space on my computer. My computer does not recognized that either of the drives exists. I cannot not find them anywhere of the hardrive. I can not remove or Install either, because th computer cannot find a drive where the software may be. I have taken that hard drive out and replaced it with another one and it works wonderful and not problems at all, therefore I know there are some importmant files missing but I don't know how to find or download them.
