 |
|
Hello,
I am having a little problem with my writemaster DVD writer (IDE). It is connected to a Promise IDE controller as well as the Hd which works fine. dmesg tells me:
| Code: |
Probing IDE interface ide2...
hde: Maxtor 6K040L0, ATA DISK drive
ide2 at 0xc800-0xc807,0xcc02 on irq 11
Probing IDE interface ide3...
hdh: TSSTcorpCD/DVDW SH-S162A, ATAPI CD/DVD-ROM drive
ide3 at 0xd000-0xd007,0xd402 on irq 11
Probing IDE interface ide0...
Probing IDE interface ide1...
hde: max request size: 128KiB
hde: 80293248 sectors (41110 MB) w/2048KiB Cache, CHS=65535/16/63, UDMA(100)
hde: cache flushes supported
hde: hde1 hde2 hde3 hde4
hdh: ATAPI 40X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache
Uniform CD-ROM driver Revision: 3.20
|
So it seems that the drive is being recognized and the driver is being loaded. Even a device /dev/hdh is assigned, but when the boot is complete, there is no device file called hdh:
| Code: |
localhost ~ # ls -l /dev/hd*
brw-rw---- 1 root disk 33, 0 Jun 21 2006 /dev/hde
brw-rw---- 1 root disk 33, 1 Jun 21 2006 /dev/hde1
brw-rw---- 1 root disk 33, 2 Jun 21 2006 /dev/hde2
brw-rw---- 1 root disk 33, 3 Jun 21 2006 /dev/hde3
brw-rw---- 1 root disk 33, 4 Jun 21 2006 /dev/hde4
localhost ~ #
|
I am confused, does anyone know how to solve this? Any ideas?
Thanks,
Sol

Perhaps udev isn't fully populating the /dev directory.
I'm not in front of a Gentoo box at the moment as I am at work.
Can someone else pehaps post the major and minor device numbers for the cdrom device.
S.o.l.a.r.i.s. can then try creating the device file manually with the mknod command.
This will at least verify the kernel is talking to the device.

Try this to manually create the device nodes:
| Code: |
# cd /dev
# MAKEDEV hdh
|
That will create all the /dev/hdh* device nodes. Try accessing your drive now.
You might check to see if udev is even running:
| Code: |
# ps -ef | grep udev
root 17387 1 0 Jun08 ? 00:00:00 /sbin/udevd --daemon

I had a analog problem and solved it with this thread. My CD-Drive is accessable at /dev/hdc, but I have no /dev/cdrom device. Is it possible to solve this? Sure, I could append "ln -s /dev/hdc /dev/cdrom" to my /etc/conf.d/local.start, but it wouldn't be nice  |
