I have a DVD-RW as the secondary master (would be /dev/hdc) and a DVD ROM as secondary slave (hdd). Now the DVD ROM drive (/dev/hdd) gets detected just fine.

The DVD-RW device is not detected, i.e. /dev/hdc is not being created.

I know the device works as it works in Windows XP, and it has worked with previous installs of linux.

The device is a LG DVD-RW.
uname -a: Linux debian 2.6.8-1-386 #1 Thu Nov 25 04:24:08 UTC 2004 i686 GNU/Linux

I'm really stuck. I've tried compiling and using newer kernels, but get the same problem.
I've tried passing: /dev/hdc=ide-cd as a boot parameter, with no luck.

I don't see how this could be a kernel issue though, I mean its just creating a device, it shouldn't need any fancy modules for that, should it?


Any ideas?

What does "dmesg | grep -i dvd" output?

What have you got in your /etc/fstab?

mike@debian:~$ dmesg | grep -i dvd
hdd: SAMSUNG DVD-ROM SD-616Q, ATAPI CD/DVD-ROM drive
hdd: ATAPI 48X DVD-ROM drive, 512kB Cache, UDMA(33)



fstab:

# /etc/fstab: static file system information.

# <file system> <mount point> <type> <options> <dump> <pass>

/dev/hda1 /media/ntfs ntfs ro,user,noauto 0 0
/dev/hdb2 /media/shared vfat uid=1000,gid=root,rw 0 0

I don't think it is the fstab file as fstat needs a device before it can mount anything.
The device is not being created at all.

I would suggest that you add a line in /etc/fstab:

/dev/hdc /media/cdrom2 iso9660 rw,user,noauto 0 0

I don't know how up-to-date you man pages are but you should read man mount(8) since my SuSE help man pages go into great detail of the options for mounted devices.

I added

/dev/hdc /media/cdrom2 iso9660 rw,user,noauto 0 0

to /etc/fstab.

That didn't help. It's still looking for a device that doesn't exist.

i think you have to mount it: [put a disk in the drive first, and allow it to spin-up]

mount /dev/hdc /media/cdrom2

then:

mount

which should report all the mounted drives.

Incidentally, when you have a cd in this 'invisible' drive what is the output of: cat /etc/mtab ?

Exactly the same problem here. Everything was OK but now my NEC 2500 is no detected.
If I put a disk in the drive and type mount I get

/dev/hdc on /media/dvdrecorder type subfs (ro,nosuid,nodev,fs=cdfss,procuid,iocharset=utf8)

but I cant use the drive.

Any ideas?

What does your mtab show? You may need to insert a dvd into the drive for it to turn up. Do you have suseplugger active on your taskbar?

Drive had a disk in and susuplugger was running. I found the solution, i only had to change boot options from bios and set first hd and then CD drive (!!!!). Now it is OK.
