Hi the list, First of all, I little browsed archives and Raoul's howto, but unsuccessful :-( My setup : * kernel 2.6.17.6 (same on last 2.6.17.10) on i686 compiled by me with udf & packet-writing support (I don't use udev) * udftools 1.0.0b3-11 * cdrecord 4:2.01+01a03-5 * ASUS DRW-1608P3S Nota : burning CD & DVD works fine. * cdrecord -scanbus dev=ATA Cdrecord-Clone 2.01.01a01 (i686-pc-linux-gnu) Copyright (C) 1995-2004 Jrg Schilling scsidev: 'ATA' devname: 'ATA' scsibus: -2 target: -2 lun: -2 Warning: Using badly designed ATAPI via /dev/hd* interface.

Re: udftools/cdrwtool standard compliant CCB patch

Oh, and I remembered I had uploaded the package here: http://revu.tauware.de/details.py?upid=1688 If you use ubuntu or debian you should be able to build the package with pbuilder and install it with dpkg. Here are the changes I made: * Fixed a few assumptions about packet size in cdrwtool that caused it to break when using packet sizes other than 32 sectors * Set default uid/gid to -1 instead of 0 for file entries created by cdrwtool and mkudffs * Documented -z ( packet size ) switch for cdrwtool in the man page * Added new single argument use case to pktsetup where you only have to specify the cdrom device to bind to, and a pktcdvd device will be auto assigned. * Fixed FORMAT UNIT command used by cdrwtool to comply with MMC-5. The old command wasn't quite valid according to MMC-5 and only worked on some drives.

reliability of dvd+rw
by martin 27 Aug '06

27 Aug '06

Hi, I thought I'd share with the list the problems of using +rw as an archive medium. Disks I've written about 6 months ago seem to have problems reading. Also even if you just mount media read only the seem to suffer from the laser reading and can degrade whist you use them, e.g. reading a part of the disk repeatedly causes the disk to fail at that point. I might just be very unlucky but this seems true for a few types of media I own. -- M

No, there is no bad idea, is just because we use to format a udf DVD, cause we can carry the burner to everywhere, and the problem was fixed.!!! upgrading to a newer firmware version on my burners it also has more speed options over thoose new HI6X ridata, now I can go for more :P. :) :) ;) Thanks. -- Gustavo Guillermo Pérez Compunauta uLinux www.compunauta.com
