I'm trying to create an image file from a CD mounted in a CD burner /DVD ROM drive, but I keep getting error messages when dd tries to read the CD disk. I'm using the dd command: dd if=/mnt/cdrom of=/temp/my_image.img bs=18k or dd if=/dev/hdb of=/temp/my_image.img bs=18k My operating system is Red Hat 9 installed in hda9. The cdrom does not have scsi emulation. I removed that command from the Grub boot because I got worse error messages when it was in effect. The drive is defined in /etc/fstab as: /dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0 The error messages all look like this: hdb: command error: status=0x51 { DriveReady SeekComplete Error} error=0x54 Is there another way to create an image file from a CD without dd?
