What is BitLocker Drive Encryption? It is a system-wide encryption that uses a string of characters as a voucher to ensure that your mobile storage facility can be lost without revealing the data. In Win8, this feature has a better experience than previous versions, so let's take a look at how to encrypt our USB drive using BitLocker driver encryption.

The recovery key is to ensure that we use a string of characters to unlock the encrypted drive when a credential (password or smart card) is lost. This recovery key can be saved in our Win8 Microsoft account, can be saved as TXT file, can be directly printed out. It is worth noting that the way to save to a Microsoft account is to be aware that this option is not available if it is a domain account. After you have selected the item to be saved, we can also save it as a TXT file, or print it directly, after the backup is complete, click Next.
