CD-RW drive not recognized (Answered)

[gs]

I am having trouble using my CR-RW drive. It worked fine under RH 9. After switching to Fedora it is not available, and it does not show up in the hardware browser. When I switched to Fedora I did a clean install, with pretty much everything the same except that I installed to a logical volume.

When I boot up I get the following messages about my CD drives:

localhost kernel: hdc: HITACHI DVD-ROM GD-7000, ATAPI CD/DVD-ROM drive
localhost kernel: hdd: SONY CD-RW CRX185E1, ATAPI CD/DVD-ROM drive
localhost kernel: hdd: set_drive_speed_status: status=0x51 { DriveReady SeekComplete Error }
localhost kernel: hdd: set_drive_speed_status: error=0x04
localhost autofs: automount startup succeeded
localhost kernel: ide1: Drive 1 didn't accept speed setting. Oh, well.

I noticed that a couple of earlier messages also referred to "hdd".

localhost kernel: Kernel command line: ro root=/dev/Volume00/LogVol00 hdd=ide-scsi rhgb
localhost kernel: ide_setup: hdd=ide-scsi

Did you make any settings in /etc/sysconfig/harddisk*?

What happens if you remove the "hdd=ide-scsi" kernel parameter in /boot/grub/grub.conf?

Everything worked just fine. Thanks for the tip.

When I tried x-cd-roast i got a scarry warning about the lack of scsi-emulation, but eveything seemed to work anyway.

Originally the ide cd-driver didn't have writing ability. As a workaround the scsi emulation (ide-scsi) was born. The emulation should become obsolete with the 2.6 kernel which has native ide cdwriting. I'm not sure if this has been backported to the current fedora kernel, but your experience seems to hint at that.
