I recently damaged my external harddrive interface, by dropping it, and everytime I plugged it in my machine immediately switched off. I have since had it repaired, but when I got it back it isn't quite working properly. It is showing up, and so are most of the files, but some folders are not showing any files in them. Its mostly folders which have mp3 or other media files which I have opened in rhythmbox and vlc. It also did a weird thing before they disappeared and if I was listening to music from it and then openend a folder to view other files on the drive, rythmnbox would lose the files suddenly... I don't know what to do.
