Question

What are the differences between the encryption modes "Partitioned", "Standard", "Boot Protection" and "Twinboot"?

Answer

Please find a detailed description about the different encryption modes below:

Partitioned
In this mode, SafeGuard Easy only applies the encryption to individual partitions. You should select this setting if your hard disk drive(s) has/have several partitions and you do not want to encrypt
all of them. In the Encryption settings you decide which partitions you want to encrypt.

Full disk encryption
All hard disks connected to your workstation are completely encrypted. SafeGuard Easy automatically recognizes whether your computer has one or more hard disk drives. The program can be installed under Windows on systems with up to four physical hard disk drives. If more than four hard disks are identified, SafeGuard Easy discontinues the installation procedure. Up to eight logical partitions can be present on each of these hard disks.

Boot Protection
Boot protection ensures is that no-one without the appropriate authorization can boot the computer from a system floppy disk/CD/ DVD to access the computer’s hard disk. Boot protection is only effective when combined with activated Pre-Boot Authentication (see ’Switching on password at system start (PBA)’). Boot Protection completely encrypts partitions that are not formatted or that it cannot identify.
In the case of FAT and FAT32 the system areas are encrypted. In the case of NTFS, the partition is encrypted from the start of the partition to the end of the MFT (Master File Table).

Twinboot (available with two primary partitions only)
If you select this option, two partitions are generated. One is encrypted, and one is unencrypted. Both must be bootable primary partitions. If the PC is booted from the encrypted partition, there is no way of accessing the unencrypted partition, and vice versa. In this way private data can be kept quite separate from commercial data.
If the PC is booted from the encrypted partition, the user must enter the SafeGuard Easy password for PBA. There is no SafeGuard Easy password protection for the unencrypted partition.
