DVD Blanking Produces Unrecognized Disk
Last modified: 2015-06-09 10:12:58 UTC
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.1 (KHTML, like Gecko) Chrome/4.0.220.1 Safari/532.1 After blanking a DVD+RW, either from Brasero or the GUI that pops up when entering a rewritable disk (I think it is Nautilus that shows the GUI), the disk is completely unrecognized. Details: The blanking process (both fast blanking and full blanking) finish without indication of errors and the dialog says that the disk was successfully blanked. After blanking, inserting the blanked DVD does nothing. It does not mount as a Rewritable DVD, it does not mount under /media or anywhere else I could find. Loading Brasero says that there is no DVD in the drive (or it asks to insert one) although the disk is physically there. Strangely, it can be forcibly written with wodim from an ISO image but wodim reports an error saying that it could not get the disk size. Please let me know what (and how) additional information I can provide to help with this. It happens every single time a DVD is blanked. I tried with 2 drives: an internal IDE NEC 3550 and an external USB Toshiba Slimline. Same problem with both drives. Reproducible: Always Steps to Reproduce: 1. Insert a DVD+RW into an optical drive. 2. Open Brasero (can also be done with Nautilus Tools menu IIRC) 3. Select Tools->Blank 4. Leave Fast blanking option or remove it, the problem still happens. 5. Wait for the process to finish. 6. Try to burn something (Brasero says there is no disk) !!! 7. Eject the disk. Note that the disk can be ejected even though a bug exists for this not being possible, when the disk is not recognized it can be done! 8. Put back the disk in the drive. 9. Nothing happens. 10. Open Brasero anyways. 11. Goto Step 6 ;) Actual Results: It is no longer possible to burn to the disk. Expected Results: To have the blanked disk recognized, mount as a DVD+RW Blank Media and that Brasero lets me choose the disk as target for burning.
Now that I replaced the IDE burner with a SATA burner, the behavior is different (and I would say even worse): - After blanking the drive is still spinning with the access light on. - The disk cannot be ejected, even after a reboot. Power cycling works though. This is with a Pioneer BDR-208BKS if that makes a difference. Please let me know if there are any further tests to do.
Created attachment 332726 [details] Error while Rewriting Additional error which may be related: In Brasero one can burn and over-write a rewritable by creating a new project and choosing "Blank" from the popup that appears when the disk is not blank... This causes the disk to be blanked and burned despite showing the following error (See screenshot): Unable to mount Blank Optical Disc DBus error org.gtk.Private.RemoteVolumeMonitor.NotFound: The given volume was not found. ...Brasero then proceeds to do the integredity check though as if it was mounted.
I confirm that this problem also exists in the final version of 11.2. Growisofs keeps running after brasero says dvd blanking is complete. Killing growisofs manually using system monitor [or kill] results in the disc being ejected. After inserting the dvd back, I found that the dvd was blank and worked correctly.

I have no idea what brasero or growisofs do when you tell it to "blank" the media. Cdrecord will overwrite the medium or parts of the medium with nulls and it will tell you that it _simulates_ blanking by overwriting. If growisofs hangs for ever, it is broken and it may make sense to use cdrecord instead. Regarding the ability to "detect" the medium: unless you look into toe recorded data, you cannot distinct a properly written medium from a medium that was overwritten by nulls. If the system does not like to use the medium anymore after the overwriting did finish, this may be just another bug in hald. Could you manually call cdrecord -v blank=fast on such a medium and try again? Please note that you need to use the original cdrecord from ftp://ftp.berlios.de/pub/cdrecord/alpha/ http://cdrecord.berlios.de/ or the SuSe binary packages as wodim does not support DVDs.
Tried the cdrecord binary and I got: Error: this media does not support blanking, ignoring. This drive or media does not support the 'BLANK media' command Also note that since I changed drives, trying anything after blanking requires power-cycling the system as the drive locks up and never releases. If I try cdrecord anyways, it says that cannot obtain access to the drive. Out of criosity I tried with CD+R/W and it works perfectly. Only DVD+R/W are giving this trouble in 11.2 (it worked perfectly in 11.1 though).
Well, it is obvious that you did _not_ use cdrecord. If you post the whole original output, we can point you to your problem......
Issue hasn't been updated for almost six years, so I assume it's solved or not relevant anymore. Feel free to reopen.
Because wodim and all other programs from "cdrkit" are unmaintained by their creators since May 2007, SuSe did finally introduce the original cdrtools again in summer 2013 after SuSe legal did verify that there of course never was a license problem (as claimed by the wodim people). Maybe it is a good idea to now remove cdrkit based packets, mention the facts on a easy to explore place and close cdrkit related bugs?
