					How to Password Protect and Partition a USB Flash Drive
Knowing how to password protect and partition a USB flash drive is very
important to the safety, integrity, and manageability of your data.
When you partition a USB flash drive, you make it so that you can write
software into your flash memory while at once running software in another
bank of your flash memory (thus you will need a flash memory with at
least two banks; one bank = four memory chips). Partitioning is used to
enhance manageability, performance, or data availability.
The BIOS command for partitioning your USB flash drive is: Router
(config) #partition flash partitions [size1 size2]
Note: if you are running a Cisco 1600 or 3600 series router (modular,
multiservice access platforms), your command would be: Router (config)
#partition flash-filesystem: [number-of-partitions] [partition-size]
There is software called BootIt that you can download and use to cause
Windows XP or Vista to allow you multiple USB flash drive partitions by
"Flipping the Removable Bit" that restricts partitioning. However, this
software is potentially harmful to your flash memory drive and is not
recommended. Two other flash memory partition software packages that are
more reliable are Advanced Partition Manager 6.0 (lets you create, copy,
resize, and move hard drive partitions without data loss), and Rohos Mini
Drive (lets you create a password protected USB drive partition on a
guest computer).
Cisco routers permit more than two flash drive partitions (it all depends
on how many banks your flash drive has). Every other platform will permit
just two partitions.
For password protection of your USB flash memory drive, there is a free
program called Cryptainer LE that many people use. Now, to use this
program you need to slice up your drive into segments (the software does
that for you), but the maximum volume size per segment is 25Mb--meaning
that a lot of files that aren't the usual text files can't be protected
unless you use multiple drives, which is very cumbersome. Another program
that is similar but isn't quite as restricted is Folder Lock, which
allows you to set up a password protection system on your PC and then
export it to your USB flash drive and then put different folders under
digital lock and key in different "lockers".
Another program called Securestix (not free) let's you pick and choose
which USB flash drive files you will password protect. Let's face it:
some files that are highly valuable to you just don't have any meaning to
a would-be identity thief.
Some flash memory drive devices come with password protection software.
These typically allow you to designate some files as "public" or
"private", and some might even come with fingerprint reading security
programming.
Again, knowing how to password protect and partition a USB flash drive is
important knowledge that allows you to operate your flash drive with
safety and better performance.
