How do I prevent a memory card from mounting as read-only in Ubuntu Linux?

Question

I'm using Ubuntu 9.04 and when I try to mount an SD card with the GUI I have to type sudo mount -o remount,rw /media/disk before I can write anything to the card. Is there a hidden setting to make it mount read-write?

Answer 1

I ran sudo fsck -a ... on the offending device. After fixing the file system corruption it mounts read-write. I had the problem again, and fixed it again with fsck. Will have to be more careful about always ejecting properly.

Answer 2

Did you check the write protection hard-switch on the sd-card reader adapter? That was the problem for me.

Answer 3

i was just looking for this as an eee pc specific problem and came across this:

Open terminal.

type in

cd .. 

until you are at your file system level, ie your cd .. just returns to where you are at.

Type in

cd /media

Type in

ls -l 

to see if your disk is there, usually labeled as disk. You will see something like:

drwxr-xr-x 3 root root 4096 2008-01-20 09:53 disk

Now you will need to change premissions,

Type in

sudo su 

and your password. Type in

chown <your user name> <disk name>

ie:

chown user disk

Now type in

ls -l 

and you should see the change.

ie: drwxr-xr-x 3 user root 4096 2008-01-20 09:53 disk
