This is the fastest , lowest cost way to hook a HDD to a PDA .
Linux will run a Forth in this box .
You will need to increase the battery size as all pocket devices
today eat batts in minutes .
with external battery pack you could run for 2 hours .

Dont believe wiki , the HDD is easy to hook , you only need
a USB hub to the EXT connector on bottom .
But no one makes a hub with that connector , so go create
it or buy $50 BreakOutBox plus cable
