My 10.04 64-bit desktop has been auto-mounting USB devices (flash drives and my mp3 player) as read-only for some reason. I had this issue happen once a while in the past, so I simply re-mounted it as rw.
However, even manually mounting these devices as rw does not solve the problem. I ran a few commands ahead of time to give you an idea of what we're looking at:
The device currently in question is definitely already mounted rw, but the system returns a Read-only flag. I tried searching the net for the answer to this to no avail.
mike@mike-desktop:~$ mount | grep -i 36CB
/dev/sdc1 on /media/36CB-D1A8 type vfat (rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,flush)
mike@mike-desktop:~$ touch /media/36CB-D1A8/wut.txt
touch: cannot touch `/media/36CB-D1A8/wut.txt': Read-only file system
mike@mike-desktop:~$ ls -l /media/36CB-D1A8/
drwx------ 3 mike mike 4096 2010-09-18 16:33 home
mike@mike-desktop:~$ chmod 775 /media/36CB-D1A8/*

mike@mike-desktop:~$ sudo chmod 775 /media/36CB-D1A8/

Help would be greatly appreciated!
