About BitLocker in Win7?

Question

I recently bought a External Hard Drive. Since it is portable, it's very risky to save important information on it, so I'm exploring it and I found the "BitLocker" when I right clicked the drive. Without more information about that thing, I just run it, I input passwords, and now it is encrypting my drive.

I know its for security, but I don't know if it's ideal to apply it in an external drive?

Do you think what I have done is right or wrong?

It still encrypting and I think stopping it would damage my drive..

So Please give me some information about it and what is the advantages and disadvantages of it???


Thanks yoU VERY mUCh!!!

Answer 1

The real advantage is to keep your data secure (especially on an external drive).



The biggest drawback, though, is that the encryption/decryption process will greatly affect the file access speed.



By the way, be really careful not to interrupt the process as your data could be unrecoverable.

Answer 2

BitLocker is a security feature included in Windows Vista that can prevent your data from falling into the wrong hands by encrypting it, even if your computer is lost or stolen.

it will not destroy ur data. we use it for data security purpose.

BitLocker Drive Encryption is a full disk encryption feature included with the Ultimate and Enterprise editions of Microsoft's Windows Vista and Windows 7 desktop operating systems, as well as the Windows Server 2008 and Windows Server 2008 R2 server platforms. It is designed to protect data by providing encryption for entire volumes. By default it uses the AES encryption algorithm in CBC mode with a 128 bit key, combined with the Elephant diffuser for additional disk encryption specific security not provided by AES.[1][2]



BitLocker is available only in the Enterprise and Ultimate editions of Windows Vista and Windows 7.[1] Users of other versions of Windows that don't include BitLocker could use a 3rd party encryption program to satisfy the need for full drive encryption (see Comparison of disk encryption software at the bottom half of this page). In the RTM release of Windows Vista, only the operating system volume could be encrypted using the GUI and encrypting other volumes required using WMI-based scripts included in Windows Vista in the %Windir%\System32 folder. [3] An example of how to use the WMI interface is in the script manage-bde.wsf, that can be used to set up and manage BitLocker from the command line. With Windows Vista Service Pack 1 and Windows Server 2008, volumes other than the operating system volume can be BitLocker-protected using the graphical Control Panel applet as well. [4]



The latest version of Bitlocker, included in Windows 7 and Windows Server 2008 R2, adds the ability to encrypt removable drives.
