Dealer recommends 2GB apparently
On another forum others have used 2.5 laptop drives with external power, so to be honest I have no idea what the limit is...
Only problem is it wants to create a library and that might take a while with 160gb drive.
I think they say the limit is 32GB as this was the limit windows xp could format in FAT? 3rd party software tho you can format as much as you like...
: Bottom line just stick with a 8GB memory stick and you will be fine
