exploration of the drive suggests to me that my problem is but a symptom of a greater problem, the likes of which i couldn't begin to understand, in my noobishness.
most of the folders in my \music directory won't open or delete because they are "corrupted and unreadable". also, it seems to have 2 iterations of each folder (2 folders named "Beck", "Opeth", so on), both unreadable. also, the "Angra" folders are openable, and each contain only a file named PPOS(followed by a character the reply box doesnt like).
