my cdrw and oringinal software for burning were working fine until two weeks ago when i started having problems with puter, had to use restore disk and did a full restore. have a compaq presario w/amd athlon 500mhz processor and cdrw that came with it. am running windows 98se. my problem is the burning program "ce quadrant" doesn't recognize that i have a cdrw anymore. have tried to reinstall drivers for cd from restore disk, say installed correctly, but programs don't recognize it. even tried fire burner s/w and it said no cdrw installed. ce quadrant gives me error something like can't find "scsi" and then "no cdrw installed. cd shows up in my computer and can put direct cd backup disk in and it works fine for reading. went to system devices and it shows "cdrw/dvd". started having problems when i went to use nero 5.0 after installing it, also had adaptec direct cd and burning s/w and also ce quadrant. had norton system works 2000 installed intil last night, thought that might have been problem, it wasn't. need help, i really don't want to have to use restore disk again, finally got most all s/w reinstalled after restore. cdrw works as cd-rom and light comes on at bootup but it's a cdrw and i can't use it as a cdrw. desperately need help, been pulling hair out and now don't have much left.
