How can I mount my photo camera for a write access?

Question

I plug a camera to ubuntu 11.10. It is automatically recognized and browsed with nautilus or through terminal. But when I copy files to my camera no copying happened. How can files be written to the camera?

Answer 1

You can choose different ways:

You can give write permission to mounted folder

Let say /media/cam is our mounting dir:

You can give sudo chmod 777 /media/cam -R command to make cam memory recursively writable.

Or you can mount your cam manually by giving read/write option to command, like:

Let say /dev/photo is the mountable device (Porbably it appears as /dev/sd**)

mount /dev/photo /media/cam -o defaults,user,rw

Another way is, if user permission is not granted for write, you can try write files as root:

sudo cp * /media/cam

Note: To identify which device your camera is on it may help to use sudo fdisk -l.

Answer 2

When you say " no copying happened" you either mean:

1) You get a copy permission denied error

or

2) The files appear to copy over but when you unplug the camera they are not there

For case 1, RecNes's answer about mounting the camera will work fine. For case 2, you are removing the camera before it can finish writing to your camera. Run "sync" in the terminal, then remove the camera once the command completes. Or you can run "Safely remove" from nautilus.
