1) The SD card interface on the C7/8x0 series does not support SDIO
2) The SD card interface does not support higher transfer speeds that some cards support.
3) There is an issue with at least the 860\'s where the Z will try to push/suck data faster than the interface supports (via USB drive or networking) and results in corrupted partition tables and filesystems. Symptoms include long Z lockups (waiting for timeouts) and similar effects on Windows as well.
4) Creating a new partition table on a Z requires downloading an fdisk ipk.
5) You can only fdisk while root, so to make things simple install a terminal app first.
6) The mkfs app on the Sharp rom appears to be semi-broken, you have to invoke mkfs.msdos or mkfs.ext2 or mkfs.ext3 to format a partition correctly.
7) For the love of humanity (and a poor penguin named Tux) please umount /dev/mmcdaX before you start blasting. Tapping the card icon in the corner has the same effect.
8) linux (at least on the Z) is not really hot-plug friendly. Make sure you unmount a card, even if the system is suspended, before you remove it. Except when the card is toast of course.
9) If fdisk on the z craps out, and is unable to access the device, try sticking it into windows, and disk managering it. You can always re-fdisk it again on the Z.
10) If you have another linux machine handy, it really helps to be able to call up the man pages, which are not on the Z.
11) When I go to a hot spot, I download from my cf wifi card to the sd card. Then when I pause, I switch to a cf storage card, and copy the downloads from the sd card to the cf card. That seems to avoid the \'burst pipes\' everytime I try it.
Enjoy, maybe more later.
