Song deletion/playback stops and starts

[TheAwesomestNerd]

Hello. I've been using rockbox for a while now. I have an iPod 6th gen classic, and lately, some odd reason, I've been having a couple of problems. The first problem I have is I'll go to delete a file/folder and it'll say the file is deleted, but once I go back in the folder, the file reappears again. Then, the most frustrating problem I'm having is when I play a song, all of a sudden rockbox will cut the song off, and pause for like a couple minutes, then it will resume playing again. Anyone else having said problems? If so, what did you do to fix them?
