[Bug 549550] New: DVD Blanking Produces Unrecognized Disk
http://bugzilla.novell.com/show_bug.cgi?id=549550 Summary: DVD Blanking Produces Unrecognized Disk Classification: openSUSE Product: openSUSE 11.2 Version: RC 1 Platform: x86-64 OS/Version: openSUSE 11.2 Status: NEW Severity: Normal Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: idanan@yahoo.com QAContact: qa@suse.de Found By: --- 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. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

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.
It makes not differences, DVD+RW media _cannot_ be blanked..... 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. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
