I bought this MP3 player thinking that it would be convenient and also double as a hard disk to move files from home to work and vise versa. Since I have had the machine I have had to completely reformat it over a half dozen times (within 2 months). Currently it is not working at all. This machine has been extremely unreliable. Often I would go on a trip and it would simple not work- one then needs the CD and a computer to reformat the device before it can work again. and , after you reformat it, you have to re-install all the songs you had on there before. When it does work every time you shut it off and restart it you have to go from the beginning to get back to where you were. I thought small size and lack of features would mean hassle free use. Nothing is further from the truth. I am only upset now because I cannot find the receipt to return this junk. Please, do yourself a favor and get something else.
