[SOLVED] can't mount ATAPI cdrom /dev/hda "mount: /dev/hda: unknown device"

nass · 03-21-2011, 12:31 PM

hello everyone,
yup some still need the deprecated ATAPI drivers.

I can't mount a cd that I place in the drive.

the cdrom drive (as a device) is identified fine:

Quote:

root@halki:/usr/src/linux# dmesg | grep hda
hda: Optiarc DVD RW AD-5170A, ATAPI CD/DVD-ROM drive
hda: host max PIO4 wanted PIO255(auto-tune) selected PIO4
hda: UDMA/66 mode selected
ide-cd: hda: ATAPI 48X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache

udev doesn't create the convenient /dev/cdrom link, but udevadm returns:

Quote:

root@halki:/usr/src/linux# udevadm info -a -p /sys/block/hda/

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

I'm running a 2.6.37.2 (slackware) generic kernel. I have modified it to include ATA/ATAPI support (in kernel, not modules).

this is the relevant section, i think:

# PCI IDE chipsets support

Make sure you tick your IDE chipset. Also check that the libata module is not loaded for your IDE chipset. A lspci -k will reveal which modules are loaded. If your hard drives are on the same IDE chipset as the optical drive, you'll need to pass some boot options (libata.atapi_enabled=0, or module options in /etc/modprobe.d/libata.conf (options libata atapi_enabled=0). Or just completely disable libata if you are only using an older IDE chipset, and want to go that route

I fully understand the need for IDE/PATA support. On some chipsets and optical drives, the older IDE modules provide better support for ATAPI devices compared to libata. I've updated most of our optical drives to SATA. I recall having an issue with optical drives, libata, and an nforce chipset.

hello there,
using libata.atapi_enabled=0 at boot didn't change much

my chipset is Intel ICH7.

and from lspci -k it doesn't look like I'm using libata.atapi (in order to disable it

as for the chipset in the kernel, i have included the Intel support as well as the generic support for pci ide chipsets (the latter on a fresh recompilation of the kernel). still no luck...

I'm not sure why the libata option did not work. It has for me in the past.

Double check IDE is enabled in the BIOS.

The modules look correct - ata_piix is from libata and defined for you SATA ports, PIIX_IDE is the older module and has been defined for the IDE controller.

nass · 03-22-2011, 07:40 AM

IDE must be enabled in the BIOS. on the same IDE controller as slave I have installed an old ATA133 hard disk - it mounts fine.
I start thinking that there might be something wrong with the drive.

I'll look for another laying around and post back.

disturbed1 · 03-22-2011, 11:07 AM

That hard drive is mounted as /dev/hdb right?

nass · 03-22-2011, 11:40 AM

nass · 03-24-2011, 05:51 AM

it was the drive after all .
bummer..
