CD-Rom Mount error
 

i just recorded some files in on dvd-r , now im trying to acess and wont let me ... it says..

mount -t auto /dev/hdc /mnt/cdrom/
mount: block device /dev/hdc is write-protected, mounting read-only
mount: /dev/hdc: can't read superblock

and dmesg says ...

end_request: I/O error, dev hdc, sector 0
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown

ive tryed reading in my buddy house , windows xp , it works. all files are there , saved.

my DVD recorder is a LG 4040b and im using kernel 2.6.15.3
im usind ide-cd module. could this be a problem ?
or i might need a firmware upgrade ?

Hi
It is a DVDrom not a CDrom so you should mount it like a
/mnt/dvdrom and /etc/fstab should be modified to show that .

thats not really true - the /mnt/cdrom is just an arbitary name. you could mount it at /mnt/usbpendrive or /mnt/iloveslackware etc. also he/she is not using /etc/fstab to mount the disk as it is being mounted manually using the mount -t command.

anyway,

does it make a difference if you try 'mount -t iso9660 /mnt/cdrom /dev/hdc'??

anyway i suspect that you wrote this using k3b which doesnt care about what your fstab thinks about this device or if you passwd the ide-scsi parameter at boot time. note you need to do this if you are using a 2.4.x kernal (uname -a) or a burner won't work properly..... (check your /etc/lilo.conf if you are not sure).


so check your kernel version
check if you are passing ide-scsi to it, if it's a 2.4.x kernel

thanks for you reply.
Walman /mnt/dvdrom is just the dir where the volume is mounted. could be something else.

and im using kernel 2.6.15.3 but , with 2.4.31 (slackware default 10.2 kernel ) happens the same.it wont mount me that media, but i can mount other one. i used Gnomebaker to burn, not k3b.

im using ide-cd instead of ide-scsi , as i read , it wont need ide-scsi under 2.6.x kernels, and im passing the the parameter at lilo.conf. append=hdc=ide-cd

i guess i need to go to my neightbours to get some files ;o

i doubt you need the "ide-cd" parameter....
