I've searched up and down for someone else with the same problem as me but I seem to be unsuccessful.
I have installed a media card, unformatted, and every time I attempt to format it, my BB freezes on that menu, and only pulling the battery restarts the phone. Is my media card corrupt, or am I just being really stupid and missing something?
If your pc cannot read it, you have a bad sector on the card.
This topic has been covered, but at least you searched..
Welcome to the forum.
Does your phone boot without the card in it without issue?
