dvd rom problems

Post by **computathug** » 29 Apr 2007, 20:39

is there commands i need to use to open my cd /dvd or is it a driver problem or a cd problem. it worked before i installed debian??? i cant even get it to open unless i use a pin and at the moment cant find 1 to see if it will start a program for eg i have just downloaded backtrack and put the iso on to disk and now want to use it on my linux system. my laptop is a toshiba satellite pro a10 and i have searched to see if i can download a file for the driver and cant place any. this laptop has a broken screen and i just connect up to another monitor which is why am not bothered if i break it some more

i have checked the toshiba site as well and found no reference there to linux at all. If the drive is not available for use with linux all is not lost if i can install this to a usb drive? tx for any info

damn.. first you need to make sure that you have unmounted the cdrom before opening it if you have mounted it, and mostly CD roms are automatically mounted.. if not you need to mount them then...

But i m not sure if you're having an issue with this or your cdrom may be faulty..

usually

Code: Select all

umount /mnt/cdrom

does the trick.. provided you mounted it in your /mnt/cdrom directory

and its always helpful to use manpages...for more info on commands

yep! as far as I know CDs/DVDs are auto-mounted when they are in a drive at bootup. you can unmount it like pseudo posted or on desktop my clicking on the "computer" icon....you'll find the CD drive there, and when you rightclick on it you have options like mount/unmount and open drive...

when i right click on the cd/dvd icon i then press eject and i get the error

Code: Select all

unmount: /media/cdrom0: device is busy
unmount: /media/cdrom0: device is busy
eject: unmount of /media/cdrom0 failed

it as though the drivers arnt loaded

hmm since the device is busy you can either do a lazy unmount like

Code: Select all

umount -l /media/cdrom0

Or first check which processes are using the file system (cdrom)

Code: Select all

fuser -u /media/cdrom0

Then you can kill them by

Code: Select all

fuser -k /media/cdrom0

after this try to unmount again.. i m 90% sure it will work

P.S. you can also eject your cd rom by using eject command (not recommended before unmounting)

Code: Select all

eject /dev/<cdrom>
