Missing DVD Drive

Mithrilhall · 02-01-2007, 12:12 AM

I'm trying to follow this DVDShrink howto (http://ubuntuforums.org/showthread.php?t=27369).

I see my DVD drive listed below but shouldn't I see it in the /dev directory as hdc?

I have no hdc located in my /dev directory.

Code:

x@debian:/dev$ cat /etc/fstab
# /etc/fstab: static file system information.

Is there a /dev/cdrom and is it a symbolic link? If it's symbolic, where does it point to?

Mithrilhall · 02-01-2007, 12:53 AM

cdrom is there...

Code:

lrwxrwxrwx  1 root root           4 2007-02-01 01:22 cdrom -> scd0

Do you know if the DVD is IDE or SCSI? Because scd0 is typically a SCSI device. If DVD is SCSI, then try to mount a CD

Code:

#mount /dev/cdrom /media/cdrom0

. If it works, then change /dev/hdc to /dev/cdrom in the fstab and you should be good to go.

The DVD drive is IDE actually. Is there any way to fix this?

michaelk · 02-01-2007, 07:52 AM

Configuring the drive for SCSI emulation i.e. adding the line hdc=ide-scsi will change the device ID to /dev/scd0. 2.6 kernels do not need to use SCSI emulation.

Have you looked at this guide?

Ah....that'll probably do it. I added hdc=ide-scsi....I'll remove it and will post back my results.

Thank you.

Which IDE controller is the DVD on and is it master or slave? It's my understanding the standard is:
hda = primary master
hdb = primary slave
hdc = secondary master
hdd = secondary slave

Mithrilhall · 02-02-2007, 11:28 AM

The DVD should be on the primary master I believe...I have to open my case but...I only have the 1 DVD drive and 2 SATA hard drives.

Mithrilhall · 02-02-2007, 11:49 AM

Ok...I moved my DVD drive to IDE1 and the DVD drive is set to Master but DVDShrink still doesn't see the drive.

This is what I get when I issue "hdparm /dev/hda":

Code:

eric@debian:/dev$ hdparm /dev/hda

/dev/hda:
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 HDIO_GETGEO failed: Inappropriate ioctl for device
eric@debian:/dev$

This is what I have listed under /media:

Code:

eric@debian:/media$ ls -la

I still can't get this to work.
