Well, next day... i'm still trying to figure out the letter of the SD card. i ran the following...
dmesg | tail

mmc0: card aaaa removed
tifm_core: MMC/SD card detected in socket 0:1
mmc0: new SDHC card at address aaaa
mmcblk0: mmc0:aaaa SD04G 3.69 GiB
Can i use the "mmc0" as my drive letter?
Have a great evening!
