Just updated my old jbr 20 with a samsung 160hc 160gb drive.
Bought this usb to ide adapter for $9 no shipping.
http://www.emtcompany.com/products/adapters/dxusbide-usb-to-ide-adapter-cable.htmPlugged it in to my XP pc, did a diskpart and an h2format, copied the files, installed drive, did a firmware upgrade and now it shows 149gb!!!
This site is great, took a old jbr with bad firmware, load rockbox, update to 2900mah batteries, install a big honkin' drive, and you have a great mp3 player.
Now I am going to hook it up to my direct tv receiver and digitally record xm channels and break them up into 1hr mp3's
Thanks again ROCKBOX!!!!!!!!
