MPC1000 hard drive

i have the 20GB fujitsu hard drive, do i have to get the hdm10 in order to hook up it up? and should i get a better memory card? im new to this so help me out please. thanks.

you need the hdm10, there's a connector interface that's required.

you don't need a bigger flash card, if you find that you run out of room often, get a new one.

so i dont need a hard drive? and theres something else, it says i had 10 sec of sampling, now i have 4 sec after i put that damn flash card. how do i get my 10 seconds of free space back? thanks 4 helpin me out
