I got creative one time and tried to see if my Attache 256mb drive would show up in the ARMax memory manager--it more or less killed it. Says it is read-only now no matter what position the switch is in. All the files that were on it at the time are still present, but I can't take anything off, format it, nor add anything new to it.
I'm thinking it was just a fluke, of inserting/removing it while it was being initialized or something, since I haven't seen anyone else have a similar problem. So just a word of caution to anyone who can't easily get a replacement drive.
