IMO, the CDROM unit(s) may have given up the ghost. I've had to replace many a HP CDROM unit & burner, and other brands as well. Make sure that the unit(s) is/are properly jumpered with regards to master/slave configuratrion, though HP likes to set up the units as CS (cable select). The best way to verify its/their operability would be to download a Windows 98 boot floppy, set the PC's BIOS to "boot from the Floppy or removable media" first and then choose to have the system load the DOS support drivers for the CDROM unit(s). If the unit(S) then results as being inoperable ("No CDROM found"), and you have not made any changes to its wiring configuration, as previously described, i.e., you have not changed the cables and are sure that these are hooked up properly & a lose ribbon or power cable is not the cause for the failure and that the units jumpers are properly installed, then it's time to replace the unit(s). If under warranty, call HP and request a replacement. It's odd that both, the burner and the reader would fail simultaneously, but not impossible. Perhaps you should check each unit individually, assuring that they are properly configured and wired. Otherwise, purchase a dual layer DVD+/- CDROM+/- burner and install it in its place. I saw a generic one advertised for a mere U.S. $49.00 dollars at one of the local office supply stores this week, with warranty, of course.
