Before encrypting hard drives on a computer, we recommend making sure that the computer is not infected. To do so, start the Full Scan or Critical Areas Scan task. Encrypting the hard drive of a computer that is infected by a rootkit may lead to its inoperability.
To encrypt hard drives using Kaspersky Disk Encryption technology:
Kaspersky Disk Encryption technology cannot be used if the computer has hard drives that were encrypted by BitLocker.
If you need to exclude some of the hard drives from encryption, create a list of such hard drives.
If you are applying encryption on a drive that is already in use, it is recommended to encrypt the entire drive. This ensures that all data is protected - even deleted data that might still contain retrievable information. The Encrypt used disk space only function is recommended for new drives that have not been previously used.
This function is applicable only to unencrypted devices. If a device was previously encrypted using the Encrypt used disk space only function, after applying a policy in Encrypt all hard drives mode, sectors that are not occupied by files will still not be encrypted.
