記憶卡格式化..問題!!

Sometimes this happens and I don't even know why.
You can however try these:
1. Make sure the card is not in the "locked" position (especially on SD cards);
2. Do a quick format first, followed by a low-level format (uncheck "Quick Format" box).
Unless your card is defective, this trick should work and your card should be all cleaned and ready for future use.
