As long as the system you use the device on later can read the file system(s) then you'll be fine.
I am going to use one of my USB flash drives to boot backtrack, my only question before I do this is will I still be able to store to the flash drive when I am not using BackTrack. I just don't want to use a 16 gig flash drive just to find out that I wasted all that space. Thanks in advance.

I'm a compulsive post editor, you might wanna wait until my post has been online for 5-10 mins before quoting it as it will likely change.
I know I seem harsh in some of my replies. SORRY! But if you're doing something illegal or posting something that seems to be obvious BS I'm going to call you on it.
