What is the encryption of the whole disk?

The encryption of the entire disk is the method of data encoding on the hard disk. Unlike many encryption methods, encryption of the entire disk includes the entire hard drive rather than a specific segment. This encryption style is useful for easy -to -stolen units, such as those in a notebook or in an external unit. This encryption is usually done via software, but some specially made disks also offer hardware -based encryption.

There are two general styles of encryption of the whole disk; Those who encrypt the main boot record and those that don't. The main boot record provides several important features, but these two important for this process take the second step of the computer process with the computer and hold the hard disk partition table. In general, hardware systems can encrypt the main triggering and software systems. After turning on the computer and the basic input/on the UTPUT (BIOS) computer, the initial startup phase ended, the main record of the boot continues to start the starting process. With the encryptionThe Hardware Fields Fields appear in this step. Without this password, booting will not continue.

For the software system, the main record of the boot is generally left alone. After the BIOS completes its step, the operating system must still load. Since it has not yet been loaded, no programming will be loaded, such as the disk encryption program. It is only after the main start record is loaded is the operating system and the associated features will work.

The

encryption of the whole disk affects systemic means differently depending on the style used. Hardware encryption is completely separated from the active computer system and will therefore have a small impact on the speed of the computer and functions. Software encryption is a constantly running program and a step towards access to the disk. In general, software -based encryption will have a slight impact on the speed and stability of the system.

encryption of the whole pIt provides basic protection when the computer is turned off or introduced, but very little when the computer is turned on. When the computer is turned off, anyone who is trying to use an encrypted hard drive must provide password information. After loading the operating system, the password was used and encryption is passive. While the unit content is still technically encrypted, nothing is closed while it is actively used. As a result, this type of encryption is used more often than standard desktop systems.
