The kernel knows what a major+minor number means, but this often just deals with generic input layers like "SCSI disk" -- which these days can mean anything from USB to SATA to PATA, not just actual SCSI. That Linux is now able to treat nearly all disks so identically is mostly a good thing -- device names don't mysteriously change from hda to sda anymore -- but also means it doesn't tell you much about which driver's used.

Try lspci -k, that'll tell you what PCI/AGP/PCIE devices are being claimed by what modules. You can also explore the virtual /sys/ directories to find out more about the devices within.

       readdvd - is creating an image of your source dvd media or medias even if it has / they have corrupted blocks

SYNOPSIS

       readdvd [-l] [-h]
       readdvd -d DEVICE1 [-d DEVICE2] [-d ...] -o file.iso [-s #] [-v] [-vv]

DESCRIPTION

       readdvd reads even a corrupted dvd and writes the the result into a new image file on your harddisk.

DEVICE

       can be an IDE, SCSI, SATA, USB or FireWire connected optical drive. Not all SATA controller support all Plextor features.

       Linux:
       /dev/hdX: IDE device
       /dev/scdX: Linux 2.4: SATA, SCSI, USB device, or IDE device via ide-scsi emulation
       /dev/srX: Linux 2.6: IDE device via new ATA layer, SCSI or USB device

       OpenBSD/NetBSD:
       /dev/rcdX

       FreeBSD:
       /dev/cd: SCSI device
       /dev/acd: ATA device

       MacOS X:
       /dev/disk:

       win32:
       C:,D:,E:, ... X:,Y:,Z:

OPTIONS

       -l	 scan busses for all available CD and DVD devices

       -h	 help shows available options.

       -o file.iso
		 write data to imagefile named file.iso

       -s #	 read source media with selected speed

       -v	 use verbose mode

       -vv	 use extended verbose mode

INTERACTIVE MODUS

       q    stop reading media and exit

       w    save sector map which is currently read and continue with the next one

EXAMPLES

       readdvd -d /dev/sr0 -o filename.iso -s 8 -v
	    create an image filename.bin of inserted media in device /dev/sr0 with read speed 8 in verbose mode.
