Hi,
I am having troubles to access my ide-atapi CD-RW drive. I have it
configured as 'hdd=ide-scsi" in the kernel. I tried 2.4.3-mdk and 2.4.6-3mdk
from the cooker without any success. I had no problems under LM-7.2 with the
2.2.x kernel.
I found a similar problem report in the archive (see below) but no solution
was sugested.
The kernel seems to recognize the cdrom drive. Here what dmesg says:
<snip>
hda: ST51270A, ATA DISK drive
hdc: WDC AC28400R, ATA DISK drive
hdd: LG CD-RW CED-8081B, ATAPI CD/DVD-ROM drive
<snip>
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
Vendor: LG Model: CD-RW CED-8081B Rev: 1.00
Type: CD-ROM ANSI SCSI revision: 02
<snip>
I can see the cdrom drive both in /proc/ide/hdd and in /proc/scsi. I have a
link /dev/cdrom -> /dev/scd0. The corresponding line in fstab is
/dev/cdrom /mnt/cdrom iso9660 ro,nosuid,noauto,exec,user,nodev 0 0
The drive is recongized when I run cdrecord:
cdrecord --scanbus

However when I try to mount the drive as 'mount /mnt/cdrom' I get
mount: /dev/cdrom: unknown device
Help is appreciated.
Thanks,
Slava

ok, this is weird, I have a sony ide cdburner on hdc, and ide-scsi is all
set up, I'm running a clean install of Mandrake 8, but apparantly I've
boffed something up while trying to disable automount on my cd drives....or
not, hadn't really tried mounting this drive before either.
[root@littlebox /root]# lsmod
<snip>
ide-scsi 7568 0
scsi_mod 85312 1 [ide-scsi]
[root@littlebox /root]# cat /proc/scsi/scsi

[root@littlebox /root]# mount /dev/scd0 /mnt/cdrom
mount: /dev/scd0: unknown device
[root@littlebox /root]# ls -l /dev/scd0
brw-rw---- 1 root cdwriter 11, 0 Apr 14 07:06 /dev/scd0
mount /dev/hdc /mnt/cdrom gives the same thing, unknown device
I'm at a loss here.
In case it makes a difference here's /etc/fstab, although it shouldn't
matter when I try to mount it manually like above...
[root@littlebox /root]# cat /etc/fstab
/dev/hdb5 / ext2 defaults 1 1
none /dev/pts devpts mode=0620 0 0
/dev/hdb7 /home ext2 defaults 1 2
/dev/hdc /mnt/cdrom auto user,noauto,nosuid,exec,nodev,ro 0 0
/dev/cdrom2 /mnt/cdrom2 auto user,noauto,nosuid,exec,nodev,ro 0 0
/dev/hda6 /mnt/downloads ext2 defaults 1 2
/mnt/floppy /mnt/floppy supermount fs=vfat,dev=/dev/fd0 0 0

none /proc proc defaults 0 0
/dev/hda5 /usr ext2 defaults 1 2
/dev/hdb6 swap swap defaults 0 0
also:
[root@littlebox /root]# mount -t iso9660 /dev/hdc /mnt/cdrom
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
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?)
ide-scsi: hdc: unsupported command in request queue (0)
isofs_read_super: bread failed, dev=16:00, iso_blknum=16, block=32
Please if anyone can tell me whats wrong reply to me @
