SD card compatibility-(2kxlMCDs & tweaked 2ks)

I have an old Kodak 128MB SD card that works just fine. My new Kingston 2GB card doesnt work no matter how i format it. I get an error in formatting and the console freezes. PLEASE LIST ANY SD CARDS THAT WORK..
INCLUDE THE MODEL NUMBER IF YOU JUST BOUGHT IT. I EMAILED AKAI. ILL POST THEIR ANSWER. Keep knockin out beats. Peace

the overall consensus in this forum seems to be, don't mess with SD cards. Compact Flash is more reliable.

So even if I have a SD card that works I still should use CF? What sort of problems occur besides it not functioning?

I sometimes get loading errors with sd cards. I dont fuk with those no more
