Can't detect DVD-RW drive

dualith · 11-26-2004, 09:07 PM

I'm running an Abit IC7-G motherboard (ICH5R) with a SATA hard drive as the primary master (on SATA1) and a Pioneer DVR-106 DVD burner as the secondary master, on the primary IDE channel. I dual boot with win xp, windows can see and do things with this optical drive fine. However it seems as if my kernel can't even see this drive at all. cat /proc/sys/dev/cdrom/info reports this:

Code:

I was thinking it could be a problem with my udev rules before I saw that. Now I think that the kernel isn't detecting it at all. Am I missing an option in menuconfig somewhere? Here's a bit of my .config:

Thanks in advance to anyone that helps me, this is really frustrating

Try this as root and see if it lists any cd recording devices
cdparanoia -Qsv
or
cdrdao scanbus
or
cdrecord --scanbus
one of them should list any recording devices on your system, if all else fails, read this...

cdrecord:

I looked at that troubleshooting list, and went through each step.

Step 1: Yes I am running the kernel I compiled, yes I checked

Step 2:
cat /proc/devices gives me this:

Code:

Character devices:
  1 mem
  2 pty
  3 ttyp
  4 /dev/vc/0
  4 tty
  4 ttyS
  5 /dev/tty
  5 /dev/console
  5 /dev/ptmx
  7 vcs
 10 misc
 13 input
 14 sound
 29 fb
128 ptm
136 pts
180 usb
226 drm

Block devices:
  1 ramdisk
  2 fd
  8 sd
 65 sd
 66 sd
 67 sd
 68 sd
 69 sd
 70 sd
 71 sd
128 sd
129 sd
130 sd
131 sd
132 sd
133 sd
134 sd
135 sd

I'm pretty clueless myself as to what that means though

cat /proc/filesystems:

Code:

nodev   sysfs
nodev   rootfs
nodev   bdev
nodev   proc
nodev   sockfs
nodev   binfmt_misc
nodev   usbfs
nodev   pipefs
nodev   futexfs
nodev   tmpfs
nodev   eventpollfs
nodev   devpts
        reiser4
        ext2
nodev   ramfs
        iso9660
        udf
nodev   mqueue
        ntfs

So iso9660 is definately there.

Step 3: This is the interesting one. I had a close look at the output of dmesg and saw this, it's the only reference to anything to do with IDE/ATA devices, to save me posting my whole dmesg:

Code:

ata1: SATA max UDMA/133 cmd 0x1F0 ctl 0x3F6 bmdma 0xF000 irq 14
ata1: dev 0 cfg 49:2f00 82:7c6b 83:7b09 84:4003 85:7c69 86:3a01 87:4003 88:207f

Attached scsi disk sda at scsi0, channel 0, id 0, lun 0

I assume all the stuff regarding ata2 is to do with my dvd drive. Nowhere in my dmesg does it say the model name or even that it's a dvd drive, however. I thought of something else that may help too, the fact that I am not running SCSI emulation but I am using the SCSI driver for my SATA controller.

Try scsi emulation, or even better yet I was wondering why you have it on the primary ide? Why not just put it on the secondary ide as master?

dualith · 11-27-2004, 05:26 PM

It isn't actually the primary master, it's just the master on the primary IDE channel. I have my bios set up to automatically configure my hard drive, on SATA1, as the real primary master. Physically, my DVD drive is the primary master, but to my computer, it is the secondary master.

I will try SCSI emulation however I've heard it isn't neccessary to have it in 2.6 kernels to be able to burn cds (or even detect my drive

), so if there's another method anyone thinks should be working then please still post it, I will be very grateful

dualith · 11-30-2004, 04:44 AM

Solved, found out it's a bug with PIIX chipset support in 2.6.10-rc1

guess thats my punishment for using a testing-kernel :P
