Hello, all. I've had quite an ordeal trying to enable scsi emulation for my DVD-ROM drive. I've finally managed to do it with lots of help from alt.os.linux.mandrake, at least to the point that K3B favors it as a copy source again; but though it mounts with no problem, I get no response to attempts to read from it.
I'm running Mandrake 9.2, kernel 2.4.22-10mdk. It's a Samsung SD-608 DVD-ROM. Here's the section of /etc/fstab that refers to the two optical drives I have: none /mnt/cdrom supermount dev=/dev/scd1,fs=auto,ro,--,iocharset=iso8859-1 0 0 none /mnt/cdrw supermount dev=/dev/scd0,fs=auto,ro,--,iocharset=iso8859-1 0 0 And the pertinent /boot/grub/menu.lst entry: kernel (hd0,0)/boot/vmlinuz root=/dev/hda1 devfs=mount hdc=ide-scsi hdd=ide-scsi acpi=ht Incidentally, the CD-RW drive (/dev/scd0) reads & writes without problems. Today, noticing that a filesystem was specified in my work machine's fstab (as well as in samples offered by people who've tried to help me with this), I added one to my own fstab entry for the device, thus: none /mnt/cdrom supermount dev=/dev/scd1,fs=udf:iso9660,ro,--,iocharset=iso8859-1 0 0 Afterward, the drive just spins for several minutes and comes up with nothing. I ran a tail of /var/log/messages during one of the read attempts; this is a bit of what I got: Feb 13 18:08:32 localhost kernel: ide-scsi: expected 2048 got 4096 limit 2048 Feb 13 18:08:32 localhost kernel: ide-scsi: The scsi wants to send us more data than expected - discarding data Feb 13 18:08:32 localhost kernel: ide-scsi: [[ 28 0 0 0 0 63 0 0 1 0 0 0 ] Feb 13 18:08:32 localhost kernel: ] Feb 13 18:08:32 localhost kernel: ide-scsi: expected 2048 got 4096 limit 2048 Feb 13 18:08:32 localhost kernel: Unable to identify CD-ROM format. There were several screens' worth of output, and different values for the line 'kernel: ide-scsi: [[numbers numbers numbers]'. So now I know _why_ the drive won't read anything, but I have no clue what to make of it. Desperately hoping someone else does. Any guidance would be greatly appreciated. Thanks very much in advance.
