Encrypting External Storage Devices on Windows
Warning: encrypting your external storage devices with bitlocker will allow you to use them only on other Windows computers. Files on encrypted jump drives are read only and need to be moved to the desktop for modification.
1. To encrypt an external storage device on a Windows computer right click on the desktop icon and choose Turn on Bitlocker
2. You will then be prompted to choose how you want to unlock the drive. Select Use a password to unlock the drive, select a secure password you can remember and enter it twice. Go to Next.
3. You will be prompted to decide how you want your recovery key. I would suggest to Save the recovery key to a file, but please be careful where you are saving this key to -- do not save it to the device you are about to encrypt. Follow the instructions for saving the key or for printing it, if that is your choice. Go to Next.
4. You will be prompted to Start Encrypting. A progress bar of the encryption will appear. Note that you must not remove the external storage during encryption unless you pause the process. Once encrypted, you will get an additional notification. Now you can remove your external storage.
5. When you connect your storage to a computer, you will be prompted for your password you chose for this device. Note that you can select Automatically unlock on this computer from now on. This is for your convenience, but remember that it does negate the effect of encryption, so choose wisely before you select this option. and click on Unlock.
A bitlockered storage device can be unlocked on a Mac, but remember that if you encrypt a device on a Mac, you will not be able to open it on a Windows computer.
