Problem with external dvd drive.

Hello!

I'm using Debian Wheezy 7.1 and i'm trying to mount my external(usb) DVD. So, the first thing i did was put a DVD with data and media inside the drive, and plug him in my usb port, and here my output from terminal:

Quote:

root@robgeek:/home/rob# mount /dev/sr0 /media/cdrom0
mount: no medium found on /dev/sr0

root@robgeek:/home/rob# mount -o ro /dev/sr0 /media/cdrom0
mount: no medium found on /dev/sr0

Here my /etc/fstab

Quote:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda2 during installation
UUID=99bf9ab3-75f8-4bd0-962b-e48521415fd3 / ext4 errors=remount-ro 0 1
# swap was on /dev/sda6 during installation
UUID=2bd210fd-22d8-4a93-b225-04983ff2e0af none swap sw 0 0
/dev/sr0 /media/cdrom0 udf,iso9660 user,noauto 0 0

# /dev/sda5
UUID=B8C85F2EC85EE9E0 /media/Backup ntfs-3g auto,rw,umask=000 0 0

How can i solve this problem? I would like to read and write with this drive. Before and after i try this mounting, /media/cdrom0 is empty, but i'm sure my dvd is not empty.

Thank you!

Two things come to mind:

1. Do a dmesg and see where this dvd drive is actually ending up when it gets assigned to /dev tree.

2. Does your external DVD drive require additional power? I have one myself vhich requires a split usb cable; one plug for data, the other for power. It sounds like it's going to work if you just pluf one in, but it does not.

Have you tried

Code:

lsusb

Do you have an internal optical drive? It would make sense if /dev/sr0 is an internal drive.

Is the external DVD recognized. In addition to the lsusb command look at the output of the dmesg command.

Guys, i solved my problem.

My DVD drive requires additional power. I plugged the other usb connector and changed sr0 to sr1 and it worked.

Thank you for your answers.
