From: john on 24 Jan 2008 09:23 I cannot read a dvd on my Slackware 12 system. CDROMs work ok. Here is what dmesg says, in part: Probing IDE interface ide1... hdc: SONY DVD RW DRU-830A, ATAPI CD/DVD-ROM drive ide1 at 0x170-0x177,0x376 on irq 15 hda: max request size: 512KiB hda: 488397168 sectors (250059 MB) w/8192KiB Cache, CHS=30401/255/63, UDMA(66) hda: cache flushes supported hda: hda1 hda2 < hda5 hda6 > hda3 hda4 hdb: max request size: 128KiB hdb: 160086528 sectors (81964 MB) w/7936KiB Cache, CHS=65535/16/63, UDMA(66) hdb: cache flushes supported hdb: hdb1 hdb2 hdb3 hdb4 hdc: ATAPI 40X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache Uniform CD-ROM driver Revision: 3.20 ide-floppy driver 0.99.newide Device cdrom points to hdc. I can hard link /dev/hdc to /dev/dvd also. I can actually burn an iso file on a dvd blank using cdrecord. I did this with slackware-current downloaded as a single iso. But I can't read it or boot from it. I don't have a device /dev/sr0. I can't play a regular video dvd via gxine. I am using dvd+ style media when I burn a data dvd such as the Slack dvd. When I try to mount a video dvd via mount /dev/cdrom I get "no medium found". When I try to mount one of my freshly burned copies of slackware- current I get "Can't read superblock" When I boot from same dvd the machine simply ignores the CD/DVD drive with no message. It is possible that the bios doesn't support DVD. How would I test for that? John Culleton P. S. My cpu is AMD Athlon 780 Mhz. Any hints?

AFAIK, that is the command to use for DVDs, not cdrecord. -- Douglas Mayne

You did most likely use a broken fork instead of the useful original software. get a recent original from: ftp://ftp.berlios.de/pub/cdrecord/alpha/ compile and install cdrecord/readcd/cdda2wav suid root and things will work for you. -- EMail:joerg(a)schily.isdn.cs.tu-berlin.de (home) J�rg Schilling D-13353 Berlin js(a)cs.tu-berlin.de (uni) schilling(a)fokus.fraunhofer.de (work) Blog: http://schily.blogspot.com/ URL: http://cdrecord.berlios.de/old/private/ ftp://ftp.berlios.de/pub/schily

Why use a different program for CDs and DVDs? You just need to take care not to use software that has been broken by Linux distributors ;-) -- EMail:joerg(a)schily.isdn.cs.tu-berlin.de (home) J�rg Schilling D-13353 Berlin js(a)cs.tu-berlin.de (uni) schilling(a)fokus.fraunhofer.de (work) Blog: http://schily.blogspot.com/ URL: http://cdrecord.berlios.de/old/private/ ftp://ftp.berlios.de/pub/schily

Slackware 12.0 delivers the original unpatched cdrtools version 2.01.01a23. (In slackware-current it's now version 2.01.01a36). But it's not installed suid root. |
