I am not sure since when the filesystem on my digital audio player has been changed to be read-only. I cannot copy files into it or remove files on it.
Are there some possible reasons for the player's file system to change the permission of its file system?
I tried chmod:
$ sudo chmod a+rw SGTL\ MSCN/ chomd: changing permissions of `SGTL MSCN/': Read-only file system
where "SGTL MSCN" is the mounted point of the digital audio player.
I was wondering how to make it writable?
Thanks and regards!
