Formatting my card. (Lexar 1GB Mobile Edition miniSD)

[qanda]This question is published in the hardware section for the Lexar Mobile Edition - flash memory card - 1 GB - miniSD. Click here to view full specs.[/qanda]I have already formated my card on my phone and erased everything. And when I try to open my F drive(card) it still says I have to format it before I do anything. So I try to format it and a thing pops up saying it cant be done. Why? Do I need to download something to make it work?:confused:
