OK After playing around and reading a crap load of info on U3 and what not, I am left with the same question. What exactly makes a U3 USB drive really that much different than an ordinary USB Flash drive besides the fact that the U3 drive is/was partitioned into 2 separate file systems one of which is a CDFS and the a FAT partition.
I know that most standard USB Flash Drives can not be partitioned into more than one partition, but even that can be gotten around.
A lot of people say its Hardware that makes a U3 drive different. I kinda beg to differ. I mean granit Firmware is kinda a combo of both hardware and software together.
So what I was thinking is what is to stop anyone from being able to create a special tool/util that can partition the drive into 2 peices 1 being a CDFS and the other a FAT and presto for all practical purposes you have a U3 (clone). 
Just me thinking a little. But I tend to talk out my A$$ sometimes so bare with me.
