USB Memory stick is read-only

When I try to delete a file, I get:Cannot move file to trash, do you want to delete immediately? and whit I click "DELETE", I Get:"/media/USB...120001.JPG" cannot be deleted because it is on a read-only disk.

I can read but not write, even though directories show as not locked

Hello !

Can you please give us the results of the following commands ?

sudo fdisk -l
cat /etc/fstab
ls -l /media*

Regards,
Benoît

Permissions seem fine. Can you send us the output of the following commands just after plugging the USB key :

dmesg | tail
mount

And please try (as bobbilob user):

touch /media/USB\ DISK/test
rm /media/USB\ DISK/test

Thanks,
Marc

Hi Marc:
I hope this helps, does it look like the stick should be reformatted in
windows??
