1.2 Standard Hard Disk Requirements

Standard disks are any disks that do not provide hardware-based encryption. When used with ZENworks Full Disk Encryption, standard disks must meet the following requirements:




  • IDE, SATA, and PATA hard disks are supported. SCSI and RAID hard disks are not supported.

  • Multiple standard disks (one primary and multiple secondary) are supported in one device. When using multiple disks, all disks must be the same (for example, all IDE or all SATA).

  • Encryption of both standard and self-encrypting hard disks in the same device is not supported. A device can have standard disks or it can have self-encrypting disks, but it cannot have both.

Disk Communication Modes

  • ATAPI and AHCI are supported.

  • When using ZENworks Pre-Boot Authentication, we strongly recommend that you use the standard Microsoft drivers. Other drivers can cause issues such as CD and DVD drives disappearing.

Disk Types

  • Basic disks are supported. Dynamic disks and other disk types are not supported.

File System

  • NTFS is supported. FAT32 and all other file system formats are not supported.

System Disk

  • The system disk (operating system) must be Disk0.

Partition Tables and Partitions

  • All disks must use a master boot record (MBR) partition table. GUID partition tables (GPT) are not supported.

  • ZENworks Full Disk Encryption creates a primary partition (referred to as the ZENworks primary partition) on the system disk to store files required for encryption and pre-boot authentication. Windows supports a maximum of four primary partitions; one primary partition must be available for ZENworks Full Disk Encryption. If all four primary partitions already exist, ZENworks Full Disk Encryption cannot create the required ZENworks primary partition and encryption fails.

  • A maximum of 10 partitions can be encrypted. The partitions can be on one disk or spread across multiple disks.

Disk Space

  • 100 MB of free disk space on the system disk (Disk0) for the ZENworks primary partition that is created when the Disk Encryption policy is applied. To create the 100 MB partition, 300 MB of disk space must be available or the creation process will fail.

  • 140 MB of free disk space on the system disk (Disk 0) for ZENworks Full Disk Encryption software files.
