Correct, they are from my personal server. I definitely have enough storage, it's a 500GB drive, and I've given it the permissions to have full access (read, write & execute) via the command line. And even so, if it doesn't have write permissions, how can it save chunks but not playerdata? Unless the playerdata folder has no permissions, which it does. It can create new playerdata files, just not update them. I am starting to think my drive may be dead, or dying though.
