How to Partition a USB Flash Drive

A USB Flash Drive can be easily partitioned into a maximum of 4 partitions.All the partitions can also be accessed in Windows easily.This is possible using a tool called Bootice.

Why Partition a USB Flash Drive?

  • Only the first partition is visible in Windows.So the other partitions can be used to hide data from Windows Users
  • All Partitions are visible in Linux.So partitioning your USB Flash Drive will be useful if you only want your Linux friends to access data on your USB Flash Drive.
  • A regular windows format cannot delete the other partitions.So an average computer user can never delete the data in the other partitions
  • You can carry bootable Linux Distros and PEs in the other partitions.

Important Facts about Windows and USB Storage Devices

  3. Third Party Tools can partition a USB Flash Drive. But all partitions will not be visible.Only the first partition will be visible

  5. Filter Drivers can make USB Flash Drives appear as USB Hard Disks.Hence filter drivers allow us to partition a USB Flash Drive using Windows Disk Management.Also all the partitions of the USB Flash Drive are mounted in Windows Explorer with Drive letters.

One main disadvantage of using Filter drivers is that a reboot is required before all the partitions of a USB Flash Drive can be accessed.So if you are using some other computer,you cannot quickly access data on your other partitions.This problem is solved by using Bootice.

Filter drivers like Diskmod do not require a reboot.
