I haven't seen this problem described in the last few months of the list archive, or in the gentoo forums, so here goes:
Formats and writes of DVD+RW fail with dvd+rw-tools, but CD-RW, and DVD-RW can be written by it. Four different +RW disks from the same spindle: 3 fail today, but one succeeded about a month ago. Is this a media problem, a drive problem or software problem? I don't have other DVD writers to test with so I can't directly test the media in another drive. I also don't have other +RW media to try right now. A significant change from about a month ago was that at some point a update occurred for dvd+rw-tools. I upgraded the kernel from 2.6.9-gentoo-r9 to several versions today to see if was a kernel problem. Behavior hasn't changed with any of the newer versions. ------------------------------------------------------------ Media: Memorex DVD+RW 2.4X Kernel: Linux 2.6.10-gentoo-r2 (not sure which -rc of kernel.org this is) DVD-Writer: NEC 2500A (using ide-cd, no ide-scsi in kernel) dvd+rw-tools: gentoo ebuild -- app-cdr/dvd+rw-tools-5.21.4.10.8 cdrtools: gentoo ebuild -- app-cdr/cdrtools-2.01.01_alpha01 ## growisofs -version * growisofs by <[EMAIL PROTECTED]>, version 5.21, front-ending to mkisofs: mkisofs 2.01 (i686-pc-linux-gnu) ------------------------------------------------------------ ## hdparm dev/hdc (turning on DMA makes no difference) ------------------------------------------------------------ HDIO_GET_MULTCOUNT failed: Invalid argument IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 0 (off) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) HDIO_GETGEO failed: Invalid argument ## dvd+rw-mediainfo /dev/hdc (post format/write attempt) ------------------------------------------------------------ INQUIRY: [_NEC ][DVD_RW ND-2500A ][1.06] GET [CURRENT] CONFIGURATION: Mounted Media: 1Ah, DVD+RW Media ID: INFODISC/A01 GET [CURRENT] PERFORMANCE: Write Performance: 2.3x1385=3245KB/[EMAIL PROTECTED] -> 2295104] Speed Descriptor#0: 03/2295104 [EMAIL PROTECTED]/s [EMAIL PROTECTED]/s READ DISC INFORMATION: Disc status: blank Number of Sessions: 1 State of Last Session: empty Number of Tracks: 1 READ TRACK INFORMATION[#1]: Track State: blank Track Start Address: 0*2KB Next Writable Address: 0*2KB Free Blocks: 2295104*2KB Track Size: 2295104*2KB READ CAPACITY: 1*2048=2048 ## dvd+rw-format /dev/hdc (failed disks all at about the same %) ------------------------------------------------------------ * DVD�RW/-RAM format utility by <[EMAIL PROTECTED]>, version 4.10. * 4.7GB DVD+RW media detected. * formatting 44.0%:-[ STOP DE-ICING failed with SK=5h/ASC=2Ch/ACQ=00h]: Input/output error ## dmesg, /var/log... after format attempt ------------------------------------------------------------ ATAPI device hdc: Error: Not ready -- (Sense key=0x02) (reserved error code) -- (asc=0x30, ascq=0x02) The failed "Read Subchannel" packet command was: "42 02 40 01 00 00 00 00 10 00 00 00 00 00 00 00 " .......... lots ofthese Jan 5 00:33:37 [kernel] cdrom: This disc doesn't have any tracks I recognize! .......... lots ofthese Jan 5 00:33:38 [kernel] ATAPI device hdc: Jan 5 00:33:38 [kernel] (reserved error code) -- (asc=0x30, ascq=0x02) ## growisofs -Z /dev/hdc -J -r -l -V PhotoCab-050104 PhotoCab ------------------------------------------------------------ Executing 'mkisofs -J -r -l -V PhotoCab-050104 PhotoCab | builtin_dd of=/dev/hdc obs=32k seek=0' /dev/hdc: pre-formatting blank DVD+RW... /dev/hdc: "Current Write Speed" is 2.4x1385KBps. :-[ [EMAIL PROTECTED] failed with SK=5h/ASC=30h/ACQ=10h]: Wrong medium type :-( media is not formatted or unsupported. :-( write failed: Wrong medium type ## dmesg, /var/log... after write attempt ------------------------------------------------------------ ATAPI device hdc: Error: Not ready -- (Sense key=0x02) (reserved error code) -- (asc=0x30, ascq=0x02) The failed "Read Subchannel" packet command was: "42 02 40 01 00 00 00 00 10 00 00 00 00 00 00 00 " ide-cd: cmd 0x42 timed out Jan 5 00:46:14 [kernel] hdc: ATAPI reset complete Jan 5 00:46:29 [kernel] cdrom: This disc doesn't have any tracks I recognize!
