Question my dvd is read as hdd and my ide cd-rw is read as scsi???


hi,

here is my optical disc drives setup...
  • all my optical discs are ide
  • my cd-rw is a secondary master
  • my dvd-rom is a secondary slave

in spite of this madrake 9.1 reads this way...
  • my dvd-rom became a hdd
  • my cd-rw became a scsi

is there a problem here? what should i do to configure my drives the way they should be?

Your burner should work OK then.

According to the poster below, your DVD doesn't need scsi emulation.

Sorry, I don't have a DVD so all I can do is point again to the Linux DVD HOWTO.

I don't know if the original question got answered by the other posts but the reason that a CD writer needs to be a SCSI device is that cdrecord only understands SCSI devices. That's why the installation sets up the IDE-based writer to use a scsi emulator to make it look like a scsi device. If you look in your grub.conf, you'll probably see some "hdc=ide-scsi" in there. (If you use lilo, it's like append="hdc=ide-scsi" )

Now there is no reason to do that for the DVD. The vanilla IDE driver is fine (you won't use the SCSI-only cdrecord with this drive). That's why you see what you see, and it's all fine and as it should be.

so there's no problem at all?

then why is it that whenever i change properties in my dvd-rom icon, this window appears...

Could not save properties. You do not have sufficient access to write to /home/...Desktop/DVD-ROM Device.

however, it does not appear when i change cd-rw settings...

Do a

ls -l ~/Desktop

and then see what the permissions and owners for the DVD-ROM are, and if they are different for your writer and DVD. I bet they are. That has most lilely nothing to do with the device in in /dev/.

cd ~/Desktop
chmod 744 'CD-RW Device'

[ you need the quotes because of your apparent space in the name ]

will do it.

Good luck,

Your CD writer has to have scsi emulation or it will not work! (Well it will, but only as a reader.)

Earlier today I thought I would try to get my dvd to emulate scsi as I read that "grip" will rip audio tracks of CDs faster.

What I did was to go into KDE Control Centre and select LILO. Using administrator mode and the Expert tab, in the lines append="something in quotes" I added hdd=ide-scsi immediately after where it already had hdc=ide-scsi.

After rebooting, it took a little messing around in both the Mandrake and KDE Control Centres, but I did manage to get the cdrecorder mounted at /mnt/cdrecorder and the DVD at /mnt/dvdrom. I got rid of the original /mnt/cdrom and /mnt/cdrom2 and yes, access is definitely quicker. Grip goes about twice as fast (not touching Nero in Windows but a definite improvement). I had to edit my DVD and CDRW icons on the desktop, but now when I click on them, I get Konqueror opening and displaying a list of entries much quicker!

I had to unload and reload K3B afterwards. However, the latest version is available for Mandrake users from Texstar. If you use Mandrake go to http://plf.zarb.org/~nanardon to set up your Mandrake Control Centre>Software Install to use Texstar, Mandrake contrib, PLF, and other sources.
