I've encountered SD cards which will be recognized as a device when plugged in to a running XO-1 (though 'ls' of a filesystem on that SD card is corrupt) -- but 'fdisk' is ineffective when I want to write a new partition table (and 'fsck' appears to loop). Since otherwise I'd just have to throw the card away, I'd be willing to apply EXTREME measures to get such a card into a reusable ("blank slate") condition. mikus -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
