Hello Nolan. I'm pretty sure the "FS" in "FS panic" stands for file system. I get this too on occasion when I press the 8 key, especially when I'm listening to an audio file, I'm more than half way through that file, and that file is near the end of a large directory. If you have another flash card, with different material on it, I'd try playing that, and seeing if you still get the same behavior as you do now when you try to delete a file. It sounds like what might be going on is that the messages table in your internal flash might be slightly corrupt. If deleting files on multiple cards produces the same set of beeps and funny messages, then I'd try forcing a reinstall of the firmware to the bookport. You are running V2.2, right? Perhaps APH could comment on the proper way to force a reload of the firmware to the Bookport. I can tell you howto do the forced reload, but I don't think my instructions are the official way, and I'd like to see ApH offer some up before offering my own. P.S. How old is your bookport? -Brian
