I searched the forums and didn't see a case (with a solution anyway) like mine in which a Sansa E200 series completely ignored the microsd card. In the original firmware settings/info screen it will display 2x capacity but niether original fw nor rockbox will use it.
This what I've done so far:
Verified microsdhc formatted fat32
completely removed/reinstalled rockbox, including bootloader
wrote a few mp3s to the card via cardreader
verified msc mode
Should the microsd card show up as a separate drive letter than the sansa? The music I wrote to the card doesn't even show up in 'database'
Hopefully I've missed something silly, otherwise I am beginning to think my Sansa's card slot is busted...
Thanks,
Jim
