Hey

I've got a real problem here. I have a HP pavilion laptop with dvd rw ATA drive. The model is HL-DT-ST DVDRAM GSA T20L ATA device. The problem is that Fedora 7 fails to recognize this device. Even when i installed fedora 7 i did it by using a hard drive image coz anaconda won't recognize it as a device. its not available in the dev directory aswel.. Please guide me how can i get fedora to recognize this device.

Thanx

I have two internal optical drives: one IDE and one SATA. The IDE drive is /dev/hdd, and the SATA drive is /dev/sr0.

Run lsmod and look for drivers ide-core, cdrom, and ide-cd (the first two do not depend on other drivers; ide-cd depends on ide-core and cdrom).

if they are not loaded, then modprobe ide-core, modprobe cdrom, and finally modprobe ide-cd.

If that get's it recognozed, add an entry to your /etc/fstab. Something like:
/dev/hdd /media/dvd subfs noauto,fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0

Note: your dvd drive may show up as /dev/hdc, /dev/sr0, or even /dev/sr1. Adjust your entry in /etc/fstab to suit your situation.

As for the mount point /media/dvd, make a mount point in your system to suit your taste.

Ok i did lsprobe at first and it didnt show any of the given modules.. so I gave the commands modprobe for ide-core, cdrom and ide-cd. it loaded the cdrom one but in case of ide-core and ide-cd it said module not found. I think thats coz i dont have an ide device. My dvd rw device is SATA. so after loading the module cdrom and lsprobe shows cdrom module loaded. But in the /dev no new device is there like you mentioned..

Here is my dev directory

Just a guess, but the reason it may not be seeing those modules may be becuase starting with F7 ALL drives are seen as sdX rather than the older format of sdX (for sata) and hdX(for pata).

i have the same problem, but i am trying to install a fedora 7 on a brand new machine that have dvd rw. Is there anywhere around it so that I can install fedora 7 on this machine . Do i have to change the dvd drive in order to install the os first?

Support for F7 will be dropped in about two months(no more updates of any kind after that). F8 has better hardware support and that MAY be the easy answer.

Hmm... so u think I should upgrade to F8.. If thats the case please tell me that the softwares um been running on F7 will be compatible to F8 aswel..

It should be, but that is no guarantee. What is the software?

For a sata dvd drive, you need different driver and device files. Here is what my Suse installation shows me:
Driver: "sata_nv", "sr"
Device File: /dev/sr0 (/dev/sg0)

Try modprobe on the drivers named, then try mounting your dvd drive with a data disk in the drive: mount /dev/sr0 /media/dvd (or whatever mount point you intend to use).

ok i did modprobe. It worked fine on sata_nv but said module not found in case of sr.. I did modprobe sg instead. and there is no device with the name sr in dev list.. there is one 'sg0' in the device list. anyway after modprobe i tried to mount sg0 and it said /dev/sg0 is not a block device.. now wot do i do.?

At this point, I'm at a loss on how to proceed. I don't know what GUI or command-line applications Fedora provides for hardware detection and configuration.

So, I'll fall back to my SuSE installation and a handy little command-line tool for getting information about hardware. It's called hwinfo. You probably don't have it in Fedora (I can't find any reference for a Fedora .rpm). The tarball is available here: http://aur.archlinux.org/packages/hwinfo/hwinfo. It's a utility for probing and configuring hardware.

If you decide to try it, it can be run as user or root for hardware detection. The command is: /usr/sbin/hwinfo --cdrom. The output (assuming it detects your dvd drive) should tell you the device it requires (such as /dev/sr0) and the driver(s) required. You can use that information to edit your /etc/modprobe.conf to have the dvd drivers loaded on boot.

hmm nope that didn work for fedora .. i tried compiling its source it gave a lot of errors.. rite now um searching for a tool like that for fedora.. let me know if u find one too..

I've a similar problem with an Inoi media tank. The tank's 300GB hard drive is detected as /dev/sdc, the tank's CompactFlash reader as /dev/sda, the SmartCard as
/dev/sdb, and the dvd burner as nothing...I expected /dev/sdd but no such luck.

I've been able to add an fstab entry for /dev/sdc1 and haldaemon will mount /dev/sda1 and /dev/sdb1 with the /media/disk and /media/disk-1 mounts.

The following device files exist for the dvd:
lrwxrwxrwx 1 root root 4 Jul 1 08:15 cdrom-sr0 -> scd0
lrwxrwxrwx 1 root root 4 Jul 1 08:15 cdrw-sr0 -> scd0
lrwxrwxrwx 1 root root 4 Jul 1 08:15 cdwriter-sr0 -> scd0
lrwxrwxrwx 1 root root 4 Jul 1 08:15 dvdrw-sr0 -> scd0
lrwxrwxrwx 1 root root 4 Jul 1 08:15 dvd-sr0 -> scd0
lrwxrwxrwx 1 root root 4 Jul 1 08:15 dvdwriter-sr0 -> scd0

I created the following symbolic link in /dev which enables the mounting of the
dvd on a manually created mountpoint (or just /mnt):

ln -s /dev/scd0 /dev/sr0

(I've added this command to /etc/rc.local so that the link is always created
on boot.

But I'd actually like to figure out why fedora doesn't detect the drive
as a block device and assign it like the other 3 drives in the media tank.

By the way, the dvd is a samsung Super WriteMaster DVD Multi-Recorder with LightScribe, so I had to install lightscribe-1.4.136.1-0, 4L-1.0-r6, and update
hplip (because I think the lightscribe rpm caused my usb printer device path for
my hp printer to disappear).

Sorry I put this info in the wrong thread :|
