Need help mounting my cd burner


Hello,

I have a CD recorder that I would like to mount and start
burning CD's.

dmesg shows:

hdc: attached ide-cdrom driver.
hdc: ATAPI 32X CD-ROM CD-R/RW drive, 4096kB Cache, UDMA(33)
Uniform CD-ROM driver Revision: 3.12
:
etc
:
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54
end_request: I/O error, dev 16:00 (hdc), sector 64
isofs_read_super: bread failed, dev=16:00, iso_blknum=16, block=32


I created a mount point /mnt/cdrecorder
I issue: mount -t iso9660 /dev/hdc /mnt/cdrecorder
and get:

mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
missing codepage or other error
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
In some cases useful info is found in syslog - try
dmesg | tail or so

The dmesg info is as above.

Can someone please tell me what I should do ?

Paul

You can't mount an unformatted/blank CDROM. Try mounting one that you know is already readable. To burn a CD, try K3B under KDE....

Re:

Hey TBOne ... It mounted, and I can see the contents of a
CD. But what now ... don't I have to 'umount' that'n before
I can eject the disk ?

Yep...just issue the unmount command as "unmount <mount point>". Depending on your distro, you might be able to issue an "eject" command, which will unmount and eject the CD.

You can't be in the mount point, or have a program running from it when you try to dismount.

... I'm confused.. As you said, I can't mount an unformatted/blank CDROM. So
what good does that do me ? If I put in a formatted CD to get the device mounted,
then how do I then eject that one in order to put in a blank one ?

I guess I should have put it:

Ok, if I use an already formatted cd to get the device mounted, how do I
then spit that formatted cd out in order to put in the new unformatted cd ?

Your mounting a file system not a device. Since blank CDs do not have a filesytem they can not be mounted. CD burning software writes to the device i.e. hdc in your case.

You need to unmount the CD before you can eject it. Make sure there are not any applications accessing the filesystem including a terminal.

You don't mount an unformatted CD/DVD, and you don't need to. Put a blank media in the device, and run your CD/DVD burning program of choice (I use K3b, but there are lots of others), to write your data to the blank media. After you're done, you can then mount it on any computer with an optical drive.

This is the same as it is under Windows...you need burning programs (such as EasyCD Creator, etc.), to write to a blank CD.

Newer than newbie, denser than lead...

Hi TBOne,

I think what he was asking, and what I'd like to do is to mount the CD/DVD drive then use command line utils to write the data.

In my case, I am trying to use clonezilla (or partimage) to create an drive backup and burn directly to a DVD in the DVD drive. (I have only one hard drive on the machine, and I obviously can't create an image file on the drive i'm trying to image, so I have the Clonezilla liveCD and simply want to have it write the image to the DVD.) I have found instructions to do so using a DVD-RW (since the file system is already created on an RW), but I'd like to accomplish a similar task directly to +R or -R DVD's.

Any ideas?

(BTW the title was in reference to my density not anyone else )
