Guest supe2dresq Posted May 11, 2005 Report Share Posted May 11, 2005 hi, i'm looking for some help. previously i was able to watch dvd's on my fresh mdk 10.1 community edition... then couldn't, not sure why. so I poked around and found that all i needed to do was enable scsi emulation--bad mistake, i don't think i did it correctly, now i can't get the drive to work. upon restart i get this from KSCD CD-ROM read or access error (or no audio disc in drive). Please make sure you have access permissions to: /dev/cdrom and this when i try to mount the emulated drive (sr0): mount: block device /dev/sr0 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/sr0, or too many mounted file systems Please check that the disk is entered correctly. i did a ln -s /dev/sr0 /dev/dvd and ln -s /dev/sr0 /dev/cdrom but the links get erased upon a reboot. here's my fstab: # This file is edited by fstab-sync - see 'man fstab-sync' for details /dev/hda1 / reiserfs notail 1 1 /dev/hda7 /home reiserfs notail 1 2 /dev/sr0 /mnt/cdrom iso9660 mode=777,owner,users,nowauto 0 0 none /proc proc defaults 0 0 /dev/hda6 /usr reiserfs notail 1 2 /dev/hda5 swap swap defaults 0 0 /dev/sda1 /media/Drive_J vfat pamconsole,exec,noauto,iocharset=utf8,noatime,sync,managed 0 0 and my modules.conf: alias autofs autofs4 options ide-cd ignore='hdb' # tell ide-cd module to ignore these drives alias s00 sr_mod # load sr_mod upon access of sr0 pre-install sg modprobe ide-scsi # load ide-scsi before sg pre-install sr_mod modprobe ide-scsi # load ide-scsi before sr_mod pre-install ide-scsi modprobe ide-cd # load ide-cd before ide-scsi and my default boot option from lilo.conf: default="linux" boot=/dev/hda map=/boot/map keytable=/boot/us.klt prompt nowarn timeout=50 message=/boot/message menu-scheme=wb:bw:wb:bw image=/boot/vmlinuz label="linux" root=/dev/hda1 initrd=/boot/initrd.img append="acpi=ht resume=/dev/hda5 splash=silent hdb=ide-scsi" vga=788 read-only Its a Plextor px-708a and is recognized by cdrecord -scanbus as scsibus1: 1,0,0 100) 'PLEXTOR ' 'DVDR PX-708A ' '1.08' Removable CD-ROM 1,1,0 101) * 1,2,0 102) * 1,3,0 103) * 1,4,0 104) * 1,5,0 105) * 1,6,0 106) * 1,7,0 107) * it is located at hdb / sr0 any help would be awesome, thanks a lot.

scarecrow Posted May 11, 2005 Report Share Posted May 11, 2005 scsi emulation is obsolete/deperecated on 2.6.X series kernels, so you shouldn't use it. Are you running devfs or udev? (I think 10.1 community had switched to udev). If it's udev, then check your udev rules, the problem must be somewhere there. You can also try updating your 10.1 repos and then urpmi dbus hal HAL will take care automounting your disks. Quote Link to comment Share on other sites More sharing options...

Guest supe2dresq Posted May 12, 2005 Report Share Posted May 12, 2005 ok, checked up on the udev rules, think i got them fixed up. but i still get this: /dev/hdb: Input/output error mount: block device /dev/hdb is write-protected, mounting read-only /dev/hdb: Input/output error mount: /dev/hdb: can't read superblock Please check that the disk is entered correctly. why is that? is that fstab? if so, what should my fstab entry for my cdrom look like? thx Quote Link to comment Share on other sites More sharing options...
