All the Clips are able to reformat themselves, under their system setings.
Depending on your setup, it can be faster to load your microSD card by removing it from your player and putting it into an SD slot in your computer, or by putting it into an external SD card reader and connecting that to your computer–and then loading the card that way.
Also, I don’t know if it will speed matters, but the SD Association’s Formatter tool can eliminate issues; you might want to try reformatting the card using that at some point (it can’t hurt!).
