Cdrw works just fine and shows the files n folders in the cd. but nothing happens when inserted in DVD rom. I m pasting my post from linuxquestions. Hope you guys can help. --------------------------------------------------------------------------------- hope this info helps. fstab file /dev/hda1 / ext3 defaults 1 1 none /dev/pts devpts mode=0620 0 0 /dev/hda6 /home ext3 defaults 1 2 /dev/hdc /mnt/cdrom auto umask=1000,user,iocharset=iso8859-1,rw, 0 0 /dev/hdd /mnt/cdrom2 auto umask=0,user,iocharset=iso8859-1,codepage=850,noauto,ro,exec 0 0 none /mnt/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,umask=0,iocharset=iso8859-1,sync,codepage=850 0 0 none /proc proc defaults 0 0 /dev/hda5 swap swap defaults 0 0 output of dmesg | grep hd Kernel command line: auto BOOT_IMAGE=linux ro root=301 devfs=mount acpi=ht resume=/dev/hda5 splash=silent ide0: BM-DMA at 0xfff0-0xfff7, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xfff8-0xffff, BIOS settings: hdc:DMA, hdd:DMA hda: WDC WD400BB-00DEA0, ATA DISK drive hdc: DVDROM 8X, ATAPI CD/DVD-ROM drive hdd: CD-W540E, ATAPI CD/DVD-ROM drive hda: max request size: 128KiB hda: 78165360 sectors (40020 MB) w/2048KiB Cache, CHS=65535/16/63, UDMA(66) Resume Machine: resuming from /dev/hda5 Resuming from device hda5 EXT3 FS on hda1, internal journal Adding 511520k swap on /dev/hda5.

For example, you pop in a DVD movie and it doesn't play or get recognized? Have you tried popping in a regular data CD and typing ls /mnt/cdrom2 anything show up?

AussieJohn Posted November 28, 2004 Report Share Posted November 28, 2004 I am not certain but I think the line for your cdrom should read the same as for your cdrom2. I have never seen that line for cdrom before. I have a Pioneer dvd/cdrom in the /hdb and its line is the same as your cdrom2. In /hdd I have an LG Dual layer DVD burner and its line is identical for both DVD units as you can see from the text below. You will possibly need to go into root and type in the same text for your cdrom as it is in cdrom2 and save the change. In this case I would consider rebooting although some might say it is not necessary. I have generally found it to be necessary. /dev/hdb /mnt/cdrom auto umask=0,user,iocharset=iso8859-15,codepage=850,noauto,ro,exec,users 0 0 /dev/hdd /mnt/cdrom2 auto umask=0,user,iocharset=iso8859-15,codepage=850,noauto,ro,exec,users 0 0 I hope it helps you.

adamw Posted November 28, 2004 Report Share Posted November 28, 2004 I agree with John, that fstab line looks odd. Wonder how it got there. There's no reason it should be trying to mount the drive rw (it's a read-only drive, and even with CD writers you don't *mount* them rw, cos you don't write to the mounted volume), or with a weird umask. Let us know if what he suggested helps. Quote Link to comment Share on other sites More sharing options...
