cdburner,dvd,a drive "inaccessible"

My previously fine CD burner, dvd-rom and a: drive are all showing as "not accessible" when I try to browse to access the CD, DVD or floppy disk in them. I am running Windows XP on a Pentium 3. Already tried uninstalling CD burner and DVD in safe mode and reinstalling - no change. When I reboot the CD Burner will work one time and read a Program CD, then it goes back to "not accessible," DVD and a: drive will not work at all. Any ideas? Thanks!

 

Are the CDrom and DVD on the same IDE channel?

Have you opened up the PC to check the connections? Maybe one is loose or needs cleaning.

I was thinking maybe your IDE/Floppy controller was bad, but it seems your Harddrive is still working properly.

Have you installed anything new recently? hardware or software?

 

Thanks for the advice! I went inside and cleaned everything with no change but the software question got me thinking. My son had added the software to produce written CDs quite awhile ago. I uninstalled that and restarted and everything is okay. We had not tried to install anything new since then and installed games, etc. played fine so I wasn't really thinking of that. Thanks!
