Windows 7: Partition of pendrive

Sir, I have 4gb kingston pendrive. I want to partition it into three parts(three drives)
Is it possible if yes plz tell me how

1) Windows will not let you create or see multiple partitions on removable media. But you can do it with linux. See this page.

2) Another approach is to try and turn your USB drive into a fixed disk by ‘flipping’ the removable bit in the firmware. This is the digital flag that tells Windows whether the drive is ‘fixed’ or ‘removable’. You can do this using the Lexar BootIt utility.

Let me add that the Lexar utility may or may not work on your particular drive, so use at your own risk.

3) The safest option is to buy a few cheap, low capacity drives and use them for individual purposes.
