DVD+/-RW won't Rewrite

I recently scrapped my RH9 system and did a net install of Debian Sarge. Just before I did this, I backed up all my important data to DVD+RW's on a drive I had purchased just days before: a BTC DRW1008IM (DVD+/-RW packaged as a Pacific Digital Drive--$30 after rebates from OfficeMax!).

Under RH9 I was running the 2.4.29-1 kernel (I think; didn't save that information). My DVD drive would flawlessly write and rewrite to Fuji and Imation DVD+RW's, using dvd+rw-tools.

Now I've finally got things in Sarge situated the way I want them, but I cannot REwrite to any dvd media! I'm running kernel 2.6.7-1 (but the same things happen in 2.4.26-1). I am NOT using the ide-scsi parameters in my grub menu (it didn't work anyway when I tried). I can write to virgin DVD+RW discs with no problem, mount them, watch DVD's via ogle, etc. I would much rather not have my DVD+RW media become expensive DVD+R media, any suggestions? Here's some more information (/dev/dvd is correctly linked):

Code:

marc@pants:~$ growisofs -Z /dev/dvd -R -l -J -allow-leading-dots Documents/

WARNING: /dev/dvd already carries isofs!

About to execute 'mkisofs -R -l -J -allow-leading-dots Documents/ | builtin_dd of=/dev/dvd obs=32k seek=0'

Warning: creating filesystem that does not conform to ISO-9660.

/dev/dvd: "Current Write Speed" is 4.1x1385KBps.

:-[ WRITE@LBA=0h failed with SK=5h/ASC=30h/ACQ=06h]: Wrong medium type

:-( media is not formatted or unsupported.

:-( write failed: Wrong medium type

(This exact commandline was used earlier to burn backup discs that work great) Okay, I KNOW that this is a DVD+RW disc, there's no question. I have dvd+rw-tools 5.21.4.10.8-1, installed via apt-get. One interesting point, I tried k3b and there was no way I could make k3b find the dvd+rw-format binary (it's in /usr/bin and that's one of the paths k3b is originally configured to look in.

All CD recording via cdrecord seems to work (write to disc, blank disc, and rewrite to disc)

Any more info necessary? Any help is terribly appreciated. Everything else in this distro is working pretty much beautifully.

PS -- Apologies if this has already been discussed, solved, and dismissed--my googling must have been substandard.

At least your drive wrote to the DVDs; I'm still struggling with my drive (LG GSA-4120b) to even recognize blank media (it is very fussy).

After much googling, I come across several mailing lists posts that suggest that DVD writers need ide-scsi emulation, and thus do not work very well under the 2.6 kernel (which does away with ide-scsi).

Actually I tried the ide-scsi options, and that didn't work, although I'm not sure if my kernel includes ide-scsi. Burning regular cd's with the unit works fine using dev=/dev/dvd (instead of dev=0,0,0 or whatever you might need). Are you using dvd+rw-tools to burn (well, attempt to burn) dvd's?

Marc

I'm still farting around with the LG GSA-4120b. I had to replace it as the drive I originally bought had broken firmware; it stopped reading commercial DVDs. I installed the latest A104 firmware (had to scrounge a Win98 install to do that, ugh). Updating the firmware improved the drive's ability to recognize media, but it still is pretty fussy reading/writing to generic dvd-r.

Yes, I use dvd+rw-tools (through k3b), since dvdrecord doesn't seem to work with this drive.

Well, much to my chagrin, I "solved" my problem. Turns out every dvd has "RW" on it, and only looking at the tiny print underneath that can you see that it says "DVD+R." So, evidently I lack some measure of perception.

Interestingly enough, I still run into problems (re-)burning DVD+RW's (haven't tried DVD-RW). I figure I get aborted burns about 25% of the time, but I found I can minimize this by running "dvd+rw-format -force -lead-out /dev/dvd" a couple times before I attempt to burn a +RW.

Have you tried burning from the command line? Just type "growisofs -Z /dev/dvd -R -l -J path/to/directory" and see what growisofs reports...or does k3b show the output? I can't remember, but I recall just having a little trouble with k3b, and using the commandline, once I could remember the commands and options, worked better.

I have a LG CD/DVD rw , with kernel 2.6.8 and scsi emulation and the option hdc=ide-scsi in my grub configuration. I never tried dvd rewrite, but it shouldn't be a problem with cdrecord-prodvd

Hi,

I tried with modprobe ide-scsi and with debian sarge 2.6.8.1 kernel and gnome
could not rewrite with k3b (dvd+rw-format not found) but i could do this in a terminal with command : dvd+RW-format -blank /dev/cdrom

after i was able to write on a dvd wich have had datas in the past with k3b.

cheers for all the infos
