DVD writer+CDRW mounting/writing problems


Hi, I'm using Kanotix Linux currently and my fstab is as follows:

# /etc/fstab: filesystem table.
#
# filesystem mountpoint type options dump pass
/dev/hda5 / reiserfs defaults 0 1

proc /proc proc defaults 0 0
/dev/fd0 /floppy vfat defaults,user,noauto,showexec,umask=022 0 0
usbfs /proc/bus/usb usbfs devmode=0666 0 0

tmpfs /dev/shm tmpfs defaults 0 0
/dev/hdc /mnt/dvdburner auto umask=0022,user,iocharset=iso8859-15,udf,codepage=850,noauto,ro,exec,users 0 0

/mnt/app/2/image /mnt/app/2 cramfs,iso9660 user,noauto,ro,loop,exec 0 0
/mnt/app/3/image /mnt/app/3 cramfs,iso9660 user,noauto,ro,loop,exec 0 0
/mnt/app/4/image /mnt/app/4 cramfs,iso9660 user,noauto,ro,loop,exec 0 0

/mnt/app/7/image /mnt/app/7 cramfs,iso9660 user,noauto,ro,loop,exec 0 0

As you see, I want to read/write my dvd writer and cdrw as in Windows XP. (that means i can copy and drag etc.) I have both Benq dvdr and Samsung cdrw. How do i amend in the fstab so as to perform normal read/write access? Currently the fstab i'm using are thru cut & paste. I'm still not familiar with the command yet. Helps needed urgently. Thanks.

well these is no big deal ,u can make an empty folder in /tmp
then post the symlink of that on ur desktop,then when u drag and drop ur data in that folder,just write that folder to your CD using k3b
does windows XP do more than that??

windows Xp uses Roxio CD burning software for that and gives u an extra option of "write these files to the CD"

regards

Hi Masand, thanks for your reply.

What i actually need is to avoid using k3b but rather a direct dragging of data in folder A to folder B. I'm also not quite familiar in posting of symlink. If possible, maybe u can help me look into the fstab to see how to edit it so my dvd n cdrw will have no problem in writing data. Thanks.

What you want to do is called packet writing. I haven't set it up yet, and i'm not familiar with kanotix. I do know that the kernel needs to be set up to support this feature.

Here is a link to a page with a bit of info. It looks a little dated since i think packet writing support has been included in the kernel without the need for a patch for a while now.

http://packet-cd.sourceforge.net/
Since i just got a new dvd burner i'll have a shot at getting this working and let you know how it goes.

Ok, no luck with this yet, but i've found more detail about how this all works.

you need support for the udf filesystem. you can check this with 'cat /proc/filesystems'. Look for 'udf'

If you don't have support try 'modprobe udf'. If there are no errors check that the module is loaded with lsmod and then check 'cat /proc/filesystems' again. If this doesn't work you'll need to recompile your kernel with support for the udf filesystem

You also need packet writing support. In your kernel config this can be found under Device Drivers --> Block Devices. I compiled this as a module. It's called pktcdvd, so i run 'modprobe pktcdvd'.

Once that's done your kernel should be setup the way it needs to be.

You also need udftools which you can find at http://sourceforge.net/projects/linux-udf/

This provides: mkudffs - for making a udf filesystem on to a dvd, cd, file, etc.
pktsetup - for assigning your burner to a packet writing device node
cdrwtool - automagically set up a cd-rw disc for packet writing

So, you need to assign your burner to a pktcdvd node. Assuming your cd burner is /dev/hdc you'd type 'pktsetup 0 /dev/hdc'. This should create /dev/pktcdvd/0

Next you need to format a disc. This is the part i can't get to work! If you're using a cd-rw you can type 'cdrwtool -d /dev/hdc -q'. If it's a DVD+RW disc then do 'mkudffs /dev/hdc'. If you get an error you might need to format the disc first using 'dvd+rw-format -force /dev/hdc'. It should work the same for DVD-RW as well but i can't get it to work! mkudffs always gives the error "trying to change the type of multiple extensions". I've searched a bit but found no solution for this yet! (But quite a few people getting the same error).

Anyways, after the disc is formatted and contains a udf filesystem you can mount it like so:
mount -t udf /dev/pktcdvd/0 /mnt/cdwriter

After that you should be able to drag and drop or use cp and treat the disc like a giant floppy. Check out http://gentoo-wiki.com/HOWTO_Packet_Writing_on_CD-RW for a bit more info (although written for gentoo most info will still apply)

Good luck!

Hi dmartins, thanks for your advice. I'm not a technical guy, but just basically annoyed for the fact that i had to upgrade my system just to run the sloppy windows xp is a joke.

I'll try all those that u had posted, and hopely the compilation will not mess up the system. I'm still trying to learn more about the symbolic linkage, compiling, the make, etc.

Anyway, will try those methods and share with u the results later. Thanks.

I've tried to get this working with a CD-RW and still no go. The common error, with the DVD-RW and CD-RW seems to be 'unable to read superblock'. I then have trouble getting the disc to eject. As long as i run linux i will never run out of things to do!

I have a BENQ 16x DVD writer. It's a brand new model so this may be where my troubles are coming from.

Same here. I also just bought a new BENQ 16X DVD writer together with my old Samsung CDRW. Still figuring how to work things out.
