I just bought a Sansa E250 and installed Rockbox and it's great. Thanks to the
developers who wrote this software. I can play my OGG files, which I couldn't
do with the stock firmware.

I wanted to add a MicroSD card. Are there certain brands that will/won't work?
Does the MicroSD card need to be initialized before use?

Thanks.
