can't find my dvd drives

gilan · 04-24-2006, 08:14 AM

Hi,

I've my new pc with my new fedora core 4 installation wich can't find my dvd drives. The Hard Drive is a sata drive and 2 dvd devices are in primary ide. The bios shows:
IDE Channel 0 Master: HL-DT-STDVD-ROM GDR8
IDE Channel 0 Slave: HL-DT-ST DVDRAM GSA...
IDE Channel 1 Master: ST3160812AS (sata disk)

I installed fedora from the dvd drive, so its bootable, my windows can read & write from/to them.
From fedora, the most surprising thing is that I haven't got any hd* device in /dev directory. Some output:

dmesg | grep -i cd

Code:

dmesg | grep hd

Code:

Media directory is empty, just floppy disk, any application can interact with the dvd (as spected), i don't know what to do.

Any help will be appreciated. (Sorry for my english)

That's odd... you are saying that you can use the dvd drive OK? What is in /etc/fstab? You can also try lspci.

Ups!

Sorry, I wanted to mean that any application CAN'T (I missed 't') interact with the dvd drives. This is my lscpi output:

hmmmm... I see an IDE controller using SATA drivers.

Code:

00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) Serial ATA Storage Controllers cc=IDE (rev 01)

Anyway - I'm betting the SATA driver is claiming the IDE controller.

You may need to recompile the kernel for this one: compile the ide driver into the kernel (i.e. not as a module) but leave everything else alone.

The other way is to make sure the ide module loads first - and I don't know how to do that.

In the boot process, the root filesystem has to be mounted first - thus sata driver will load first by default.

Of course - you could always swap your hardware over so you have your root partition on an IDE drive... with the trouble installing from SATA drives, you'll probably want one ide dvd drive too.

This may even make more sence - using a small drive as hda to contain the root and swap partitions, but use SATA/RAID for the main parts you want to protect like /home ...

So your choice is kernel compile vs reinstalling.

Also please issue "dmesg | grep -i atapi" and post "/etc/fstab" and "mount" output.

Thanks for your replies, I think that recompile kernel is better to solve this problem...nevermind, I will be on it as soon as I can.

dmesg | grep -i atapi

Code:

ata1: dev 0 ATAPI, max UDMA/33

mount

I hope this help!
