Dear all,

I can't get my DVD copier work on my machine although it was working just fine before the previous reinstallation of the system:

#dmesg
...
...
ICH5: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0x0500-0x0507, BIOS settings: hda: DMA, hdb: pio
ide1: BM-DMA at 0x0508-0x050f, BIOS settings: hdc: pio, hdd: pio
hda: DV-W28EAW, ATAPI CD/DVD-ROM drive
...
....
hda: attached ide-scsi driver.
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
Vendor: TEAC Model: DV-W28EAW Rev: H.0C
Type: CD-ROM ANSI SCSI revision: 02
....
..
at the end:
sr0: CDROM (ioctl) reports ILLEGAL REQUEST.
cdrom: open failed.
ide-scsi: hda: unsupported command in request queue (0)
end_request: I/O error, dev 03:00 (hda), sector 64
isofs_read_super: bread failed, dev=03:00, iso_blknum=16, block=32

my fstab file contains:

/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0

it is not working with this configuration and when i do mount /dev/cdrom it give me the "no medium found" result although i am sure that there is a DVD media inside it.


i tried to modify the fstab entry to be

/dev/hda /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0

but that gave me another result which is:
mount: wrong fs type, bad option, bad superblock on /dev/hda or too many mounted file systems (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?)

please Help
I appreciate you response very much

Up through kernel version 2.4 the preferred method of handling IDE CD devices was using ide-scsi emulation. Starting with kernel version 2.6 ide-scsi is depricated and you should use ide support. Are you attempting to use ide-scsi emulation for IDE devices on kernel 2.6?

No, my system's kernel version is 2.4

any reply for this issue on this lovely forum?

/dev/cdrom should be a link to some other device. Try this command to see where /dev/cdrom links to:

ls -l /dev/cdrom

Also you could see whether the modules for ide or scsi are loaded with:

lsmod | less

wrong post

Dear all

I think that my problem is due to the driver of this DVD drive on the linux machine
can anyone provide me with the link to such a driver?
