Removable Media (NEC DVD+/-RW ND-6650A) stopped automounting in Fedora Core 5

infra · #1 22nd September 2006, 01:25 AM

Hi all,

This is my first post and I'll make it a point to say that I'm new to Fedora Core / Linux in general.

I've been following the resources found on this forum and it has been great, however I haven't found a solution to this particular problem yet.

Forgive the immense detail, but I believe adding any and all relevant information will give you pro's the info you need as well as anyone else encountering this problem in the future. Also, it gives me a small feeling of contribution to the community

Cheers, and I thank you for any help you can direct this way.

SPECS:
-FC5 on Dell Inspiron 9300 using Gnome

PROBLEM:
-My CD/DVD drive (Model NEC DVD+- ND-6650A) has stopped automounting
-CD/DVD icon does not appear when I double click on 'Computer'

WHAT I HAVE DONE RECENTLY:
-I installed NeroLinux last night
-I enabled DMA (NeroLinux was giving me a warning that DMA was disabled); I used the following instructions to do so: Enable DMA on your DVD/CD drive
*** EDIT: When I REMOVE the changes that the post instructs me to make, my NEC DVD drive works perfectly fine - the automount feature works correctly - The question is, how do I enable DMA to gain increased speed as well as keep the automount functionality ***

NOTES:
-After I followed the instructions to enable DMA, I rebooted and NeroLinux did not give me a message regarding DMA being disabled, however the DVD drive was not automounted - I did not even see a CD/DVD icon when I accessed the 'Computer' icon on the desktop
-I noticed when I ran HAL (command line: [root@localhost ~]# /usr/bin/hal-device-manager) that I DO NOT see my NEC DVD recorder under 'Devices', however NeroLinux picks it up when I go to Choose Recorder); I also noticed that in HAL Device Manager, I see "AT DMA Controller' listed as a Device - not sure if this means anything to you experts out there.
-I am able to mount the drive by creating another directory named "DVDRW" in /media/ and running the following command (However, I have to do this everytime to access a CD/DVD):

[root@localhost ~]# mount -t iso9660 /dev/cdrom /media/DVDRW
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@localhost ~]#

MY GOAL:
-To enable DMA (or increase the speed fo my optical drive by any means)
-I want Automount to work as it was before:
-I ALWAYS have a CD/DVD icon when I double click on 'Computer'
-The name of the CD/DVD icon changes itself according to the CD/DVD's label name
-Whenever I eject, the CD/DVD icon will remain (of course the label of the CD/DVD will detatch itself from the name of the icon)

Hello:
When you pop in a disc to your drive and it mounts, open a terminal and
type
hdparm -I /dev/hda
and what is the output?

Hey Seve,

Did you want me to run this command with or without the changes to enable DMA?

I ran the command you requested without DMA enabled, however there is no mount point at /dev/hda:

[root@localhost ~]# hdparm -I /dev/hda
/dev/hda: No such file or directory

However, I ran hdparm -I /dev/cdrom:

[root@localhost ~]# hdparm -I /dev/cdrom

/dev/cdrom:

Hello:
Well it definitely shows using_dma = 0 (off)
Have you checked your BIOS settings regarding this drive?
Most BIOS's should enable dma on boot?
Is there a newer BIOS available for your motherboard?
You could use hdparm to set dma to on if there is no option in your BIOS.
If you type man hdparm and or just hdparm in a terminal you will see the options, that are available.

Unfortunately, you can't enable DMA via hdparm:

[root@localhost ~]# hdparm -d1 /dev/cdrom

/dev/cdrom:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
[root@localhost ~]#

I mentioned this thread earlier (click here); it shows us a workaround for those who can't enable DMA simply by typing hdparm -d1 /dev/cdrom

Now, this workaround works perfectly as my DVD playback is not choppy, but I wish there was a way to retain the automount functionality for ease of use without having to manually remount the drive every time.

It seems to work for me, so I dunno?

I'm just wondering why your BIOS is not setting the mode correctly?
You may also want to see if Dell / NEC has a newer firmware for you drive?

Do you know a way of manually mounting the CD/DVD drive and have the CD/DVD icon remain after ejecting the media?

Kobnar · #10 23rd September 2006, 12:06 AM

so apperently I've learned that the reason for htis sudden change was due to the FC team changing their mounting technique to use "gnome-mount" or somthing -- my USB drives even stopped mounting... I assume this is because gnome-mount has limited support for sda drives and the sutch. The problem lies not with thie bios or the firmware -- the drive type is just not supported by the software. I've been looking for a way to configure HAL to recognize the drives with the LIBATA driver -- it even recognizes them but for some reason it doesn't mount them. Maybe if I can find out how to actually change the settings in the hal-device-manager I'd be able to fix this problem for all users of SATA cd drives.... ok... somewhat drunk and time for bed -- goodnight.

Kobnar · #11 23rd September 2006, 12:07 AM

oh and you can add it into the FSTAB but I like relying on HAL...

infra · #12 23rd September 2006, 06:41 PM

I hope you come up with something!

I noticed that, when DMA is enabled, I don't even see the drive in HAL even after I've mounted it. Maybe it's like you said.. HAL has an issue with the LIBATA driver.

I found this post by "bodger" from this thread (click )

Quote:

dave - try adding to your kernel boot line (/etc/grub.conf) the term:
hdc=noprobe

The line should now read something like this:

kernel /boot/vmlinuz-2.6.16-1.2122_FC5 ro root=LABEL=/ rhgb quiet hdc=noprobe

Although it won't read as DMA enabled, this fixed up my DVD issues.

Hope it helps.

adding hdc=noprobe to etc/grub.conf worked with speeding up my DVD drive... however I got the same results with HAL and automounting. What does hdc=noprobe actually do? This doesn't exactly tell the drive to use LIBATA does it?

I have this very same issue. The only work around I have have found is to use an older HAL rpm. The original one in fact, but this wont install without forcing the rpm.

rpm -i --force hal-0.5.7-3.i386.rpm

Use with caution! as there are side effects on my notebook with the Ati driver. Every so often the gnome desktop will fail to load with the system needing to be rebooted to fix the issue.

EDIT: editied comand for rpm

I'm trying to force install hal-0.5.7-3.i386.rpm but it doesn't seem to be overriding.
