As I read it here the idrive converts it to 128 wma when it transfers it to the onboard drive. I would not want this to happen to my music. USB SSD flash drives are getting cheap in the smaller sizes and quite reasonable in somewhat larger sizes that would be adequate for most people to fit entire collections if that were the goal.
Much, much easier than burning discs unless a person is of a mind to be stubborn. lol If thats the case I can't really cast any stones, done it myself.
