ah perfect - thanks!
for any other noobs like myself, I simply booted a knoppix live cd
, plugged in my usb drive and esata drive, used gparted to delete all the old partitions on the esata drive and create a new, single, primary, ext3 partition.
Then from the command line, from within the root of the usb drive (/media/sdd1) I ran the command [media/sdd1] "cp -aR * /media/sbc1" to copy everything to the eSata drive (/media/sbc1). Then, I simply plugged the eSata drive into the pogo plug, along with my existing 2tb usb drive I use for storage, and it started up w/out issue!
