Indicates the desired operation for target partition: create a new partition from unallocated disk space, split the target partition to create a new partition, or merge unallocated space with the target partition.
Cannot merge unallocated spaced with the operating system partition. Unallocated space is not listed if four primary or extended partitions already exist. Letters A, B, and C are excluded. If no letter is indicated, the first available drive letter backward from S is applied.
The minimum size is MB. At least 10 percent of the target partition must be free after the new partition is created. The target system has a single partition. To prepare the computer for BitLocker, you want to split the operating system partition. You want the following conditions to be true:. The target system has more than one partition. To prepare the computer for BitLocker, you want to merge unallocated space with an existing partition.
You may need to manually prepare your drive for BitLocker. At least 10 percent of the active partition must remain free after the partition size is reduced by 1. To resolve this error, move files to another partition or delete files. Occasionally, some unmovable files may prevent the tool from defragmenting and resizing partitions.
These files may include any of the following items:. This issue may occur even if the operating system is newly installed. To work around this error, use one of the following methods:. Temporarily disable hibernation option and hard disk paging.
Then, use the Windows Preinstallation Environment to delete the Hiberfil. Restart the computer in Windows Vista. When you use the BitLocker Drive Preparation tool on a Windows Server based server, you may receive one of the following error messages:.
You may have to manually prepare your drive for BitLocker. However, it is possible that you copy the binary files from an earlier release of the BitLocker Drive Preparation Tool.
Then, you will see the second error message. To resolve this issue, install the BitLocker Drive Encryption optional component. To do this, follow these steps that are mentioned in the "System requirements" section.
Insufficient disk space for BitLocker Drive Encryption to encrypt the drive. Use disk maintenance tools to repair the disk and try again. Since most large shops are going to upgrade to Windows Vista anyway, why not eschew the add-on tools and fast track the migration?
In other words, use your need for laptop encryption as a rationale to jump on the Windows Vista bandwagon in ? Now I realize that my suggestion borders on Analyst blasphemy. It is common wisdom to recommend waiting to upgrade to new operating systems while Microsoft "gets the bugs out. Clearly, I am comparing apples and oranges and am way off base. Rolling out a tactical security tool with a two-year life span is nuts.
Do you really want to install software, disrupt users, and train support staff in then throw all this effort away in mid? You can't even depreciate the software in that time frame so good luck getting this strategy by the CFO.
This ensures that the disk is encrypted at startup. Consequently, if the disk were stolen and removed to a different computer, the thief would need the recovery keys before they could read the data. Set the BIOS to boot from the first disk. Creating the BitLocker Partitions As ever, planning is the key. As you install Vista, create at least two partitions, one for the operating system one for the encrypted data. If your TPM Trusted Platform Module is not initialized, then the wizard will guide you through the initialization process.
Save the password in a folder. Print the password. Because Encrypted Hard Drives encrypt data quickly, enterprise devices can expand BitLocker deployment with minimal impact on productivity. Encrypted Hard Drives are a new class of hard drives that are self-encrypting at a hardware level and allow for full disk hardware encryption. Encrypted Hard Drives are supported natively in the operating system through the following mechanisms:.
It is important to confirm the device type is an Encrypted Hard Drive for Windows when planning for deployment. Rapid encryption in BitLocker directly addresses the security needs of enterprises while offering significantly improved performance. In Windows Server , Windows 8, or later, Encrypted Hard Drives offload the cryptographic operations to the drive controller for much greater efficiency. When the operating system identifies an Encrypted Hard Drive, it activates the security mode.
This activation lets the drive controller generate a media key for every volume that the host computer creates. This media key, which is never exposed outside the disk, is used to rapidly encrypt or decrypt every byte of data that is sent or received from the disk. Configuration of Encrypted Hard Drives as startup drives is done using the same methods as standard hard drives.
