Win 7 makes it easier to encrypt a U disk

Today's USB disk and other mobile memory than a few years ago is really the price of cabbage, a 4GU disk is just dozens of dollars, many users are accustomed to take a U disk as the home and the file between the company, but this small u disk is very easy to lose, saying storage price and data is priceless, U disk lost does not matter, But the important information inside the file for the wrong person to take away can be a big loss.

In order not to be important data leakage, many users have recourse to a variety of U disk encryption tools, but the market on the U disk encryption tools are uneven, a bit even pseudo encryption, and some will also be due to design defects resulting in the loss of the user's files, so that users do not gain, there is a security

In fact, the use of Windows7 users have a very secure encryption tool, with it, you can be assured of the encryption U disk, do not have to worry about the risk of being illegally cracked. This is Windows7 's BitLocker encryption feature.

In the Windows7 of the U disk with BitLocker encryption operation is very simple, you only need to be in the U disk on the right button menu select "Enable BitLocker", you can enter the BitLocker Encryption Wizard.

The first option is to lock the way, ordinary users choose the password to unlock the way you can, remember to set the password must be strong password to eliminate the possibility of brute force. The smart card unlock mode only applies to users who have smart cards.

(A smart card is a small plastic card that contains a computer chip.) Smart cards are usually issued by the information Technology (IT) Department of a large company. To use a smart card, you also need a smart card reader, which installs or connects to the computer and can read information stored on the smart card. )

Next is the option to save the recovery key, the so-called recovery key, in fact, is a text file, which is a string of decryption characters, users forget the password can use this string characters to decrypt the U disk, so this file needs to be properly kept, if you are sure you will not forget the encryption password you have set, you can completely remove the recovery key.

(When your computer starts, if BitLocker detects a system condition, it may indicate a security risk.) If disk errors, changes to the BIOS, or changes to any of the startup files, BitLocker locks the drive and requires a specific BitLocker recovery password to unlock it. Make sure that you create this recovery password the first time you turn on BitLocker, otherwise you may lose access to the file permanently. )

The next is a period of time waiting, waiting for a U disk overall encryption operation completed, the time spent depends on the size of U disk and transmission rate. Don't worry, that's it. The time needed to open encryption is so long, open the encryption of the U disk using the USB disk before the use is the same. When a user stores a file on a USB disk, it automatically completes the encryption process, which is just for a moment, and vice versa.

So, how to use the USB disk after BitLocker encryption? In the WINDOWS7 system, the user only need to access the encrypted USB disk, will pop up a decryption dialog box, the password can be unlocked after the U disk, then you can use the U disk as usual. This is only in the current computer to unlock the operation, not decryption operation, that is, after the unlock automatically in the background to complete the file encryption (file stored in the U disk) and decryption (file from the U disk copied to the local) operation.

If you do not want to enter the password every time, then you can check the "from now on this computer automatically unlocked" option, after inserting the USB u disk in this machine will automatically unlock.

Use BitLocker encryption U disk is not able to decrypt is not available, even to others get, no password can only look at the U disk sigh, each other can do is only the format of the U disk operation.

BitLocker encrypted USB disk when opened under Windows XP, will display a bunch of files, this is, the user needs to find Bitlockertogo this executable file and run, will open the BitLocker to go Reader, This reader is designed by Microsoft specifically for users to decrypt BitLocker encrypted USB drives in Windows XP, but it should be noted that the tool can only help users read the files in the encrypted USB drive, and not modify or add deleted files.
