ide-scsi=hdc was in the grub.conf, and was not removed during the upgrade process. After removing ide-scsi=hdc, the results from `cdrecord -scanbus` are what are to be expected.
anaconda is to be blamed
Can you attach your grub.conf?
I had a similar problem and tracked it down to an ide-scsi parameter that should not have been copied over by anaconda during the update to FC2. The entry in grub.conf as created by anaconda: title Fedora Core (2.6.5-1.358) root (hd0,1) kernel /boot/vmlinuz-2.6.5-1.358 ro root=LABEL=/ hdc=ide-scsi max_scsi_luns=3 initrd /boot/initrd-2.6.5-1.358.img hdc is a cd burner. The max luns entry is unrelated; it was added to keep a 6-in-1 USB memory card reader from producing dozens of duplicate scsi entries. You might want to roll this and other similar bugs up into a single one. There's a whole host of cdr- and dvd-related symptoms caused by the retention of that boot parameter.
