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.
