hmmm....transmission app. I got the same "read only" files problem when im using transmission, it started when i installed swapolube.

tried to fix mass storage using backupmenu.

i fixed my mass storage using a win7 pc but the problem persisted.

rebooted, uninstalled swapolube and reverted all settings to default, use transmission again and its still there.

backed up all my files, reformatted my mass storage. used transmission and everything was fine again. installed swapolube, applied custom settings on wiki, and at the time i-restarted my torrent download, the file got corrupted again and my mass storage is again read-only.

did all reformatting and stuff and did not install swapolube again.

now, im download a 6GB file using transmission and its going smooth.

NOTE: I dont blame swapolube or transmission for my problem. i just stated what caused this read-only problem to my device.
