Unable to burn at 4x using cdrecord and dvd+rw-tools
Hi, I have a small problem with my dvd recorder. It's a NEC ND-1300A (dual format). It writes DVD+/-R at 4x, DVD-RW at 2x and DVD+RW at 2.4x. cdrecord (either from cdrtools or ProDVD) reports that the drive can write at most at 2x: Cdrecord-ProDVD-Clone 2.01a26 (i686-pc-linux-gnu) Copyright (C) 1995-2004 Jörg Schilling Unlocked features: ProDVD Clone Limited features: This copy of cdrecord is licensed for: private/research/educational_non-commercial_use TOC Type: 1 = CD-ROM Using libscg version 'schily-0.8'. atapi: 1 Device type: Removable CD-ROM Version: 0 Response Format: 2 Capabilities : Vendor_info: '_NEC' Identifikation : 'DVD_RW ND-1300A ' Revision : '1.0A' Device seems to be: Generic mmc2 DVD-R/DVD-RW.

A. That may be the case. I was using Verbatim media, I bought them because they are supported by NEC [1]. Now I'm burning at 4x using Magnex DVD-R media with growisofs without problems. cdrecord still refuse to work at 4x though.

[ISOFS] Troubles with multi session DVDs.
Hi, I'm having a strange (at least for me) problem burning multisession DVD+R media: the dvd becomes unreadable after the 3rd session is burned. mount refuses to do its work, and kernel says: Unable to identify CD-ROM format. Note that there isn't any read error, so the kernel is simply unable to locate the primary volume descriptor. That happened with 3 different disks (and different data, though sessions size were similar). DVD were burned with growisofs (5.19.4.9.7) using the following command: growisofs -M /dev/hdc -J -r (-Z for the first session) mkisofs version is 2.01a29. I don't think that the problem is related to the inode wrap after 4GB because: * The 1st and 2nd sessions took about 2.6GB, the last was 1.8GB so directories should be before the 4GB boundary. * I tried the patch from Paul Serice without success.

Kernel is 2.6.6 (and 2.6.7 for the last dvd), DMA is on for both the HD and the DVD recorder. Also I don't have any problem filling the DVD in one session. The "other" OS is able to read the disk, so this may be a problem in the isofs code (that's why I put lkml on CC). Any idea of what's going on? thanks, Luca PS: cc me, I'm not subscribed. -- Home: http://kronoz.cjb.net La vasca da bagno fu inventata nel 1850, il telefono nel 1875.

Yes, I can confirm that with ide-scsi I can read the dvd without problems. Jens are you aware of this bug in ide-cd?
