To set up password on a USB drive:
Insert a USB drive, and go to Control Panel > BitLocker Drive
Encryption.
Here BitLocker To Go can be enabled for USB drive. As soon
as you do, BitLocker To Go will begin initializing your USB
drive. During the process you don‟t have to worry about any
data that is already on the drive.
After the initialization process is complete, BitLocker To Go
will prompt for a password which you can use to unlock the
drive later. You can also use your smartcard PIN to unlock the
drive.
Next to password setup, BitLocker To Go will prompt you to
store a recovery key that helps unlock your drive in case you
forget your password or lose your smart card.
Recovery Key can be saved in a file or can be printed as well.
Thereafter it would ask a confirmation for encryption process.
You’ll be prompted to begin the encryption process once you
save the recovery key.
During the encryption process, you’ll see a standard progress
monitor which tells the percentage of drive encrypted. The
amount of time that it will take to complete the process will
depend on how large the drive is.
While the encryption process is going on, status of Drive can
be seen as Encrypting in control Panel.
When the encryption is complete, a prompt would display
Encryption is Complete.
Now the drive is encrypted and password prompt on plugging
the USB drive starts from next plug in.
Encrypted USB drive would prompt to enter the password
immediately after it is inserted. The drive can be used only and
only if Correct password is entered.
BitLocker To Go encrypted drive works in Windows XP/Vista
as well i.e. it would prompt password in XP/Vista as well even
if drive is encrypted in Windows 7.
The USB drive has a closed lock as an icon till it is unlocked
and thereafter the icon changes to an open lock signifying
drive is unlocked and ready for use.
