I just downloaded Mint last night and something strange has happened (I think). I set it up manually to use a 1.5 GB swap partition, a 12 GB Linux partition, and a 135 GB data partition. The weird thing is that the data partition seems to be completely locked. I can't access the only folder in it (lost-found) and also can't add anything to it (any action gives me a permission error). Is there some way to fix this? Or is that how it's supposed to be? I'm really new to Linux, sorry if this seems stupid.
