My pc crashed whilst in the middle of a firmware upgrade. I believe from reading on various forums that my 8 gig glacier was hacked, and indeed it only had 1 gig of storage on it. I may be wrong, but it would explain why I was having bother storing mp3 on it.
The problem I have now is that I have a blank screen, white in colour! My pc recognises it, but unfortunately I can't format it or reset it, or try to update the firmware again.
