A few weeks ago I had a problem saving anything to the external SD card or renaming/deleting anything on it. All attempts resulted in error messages saying it's a read-only file system. After a reboot, the problem went away. I didn't notice it again until the past couple of days. Now it seems to be happening more frequently. It's a hassle to have to wait for the phone to reboot each time I need to fix this, so I'm looking for either a permanent fix or a way to quickly remount sdcard-ext. (removing and reinserting the physical card itself is also too much hassle because I would have to remove my otterbox case, and if you have one of those you know it's not easy to remove). Any ideas?
