usb key and protected partition. (john Brennan-Sardou)

[john brennan-sardou]

hello everybody,
Somebody has just given me a usb key with two partitions. One of them 
has a partition of 256
 megas, made under windows and the directories and the files are 
protected. How can I destroy this partition  in order to get the full 
amout of space. If I have to go by the publicity each time I use it, the 
key will find itself very quickly in the bin instead of giving me good 
music in my car. Thanks a lot and a happy Christmas to you all.  John
