Typed root, done all that, then it scrolled up loads of numbers says something about clusters being wrong etc, made a few files 0 bytes performed changes and is done, restarting it now, I'll update again after.
Yeh, it seems a whole folder of music was corrupted (that was when the N900 froze on me), even though it shows the files in the music folder they were in it says they can't be played due to the codec and they are just simple .mp3 files lol. Thanks alot for your help again, I've thanked you on every post you have made lol. Take care mate.
