Automounted USB drive is owned by root and not writable

Hi,

I've created an ext3 parition on a USB flash drive using:

chown my-user /media/CZILLA_IMAGES?

if youre talking in general about getting usb drives to mount so that theyre writeable by an ordinary user, id look to fstab or udev (depending on if you want it automounting or not)

'man mount' and a bit of trawling through udev rule examples should get you started

Unless I'm reading the initial post wrong, it's a different problem:
'/media/<whatever>' (where <whatever> is usually the label) is created upon automount.

However, the OP should mention their desktop env or at least the program used for automount.
If it's again consolekit case, 'ls -l /dev/sdc1' and 'getfacl /dev/sdc1' is of interest, probably the output of 'udisks --mount /dev/sdc1' (while still unmounted, obviously) too.

On a semi-related note: is ext3 a good idea for a flash drive ?

Even if the directory is only present when the drive is attached, the ownership and permission of the mountpoint are determined by the ownership and permission of the root directory in the mounted filesystem. Thus, it is correct for the directory to be root:root when nothing is mounted, but there is no value in having write permission there if the stick is not mounted. If the stick is mounted, then it will use the data from the mounted filesystem.
