The version of BitLocker included in Windows 7 and Windows Server 2008 Release 2 adds the ability to encrypt removable drives. On Windows XP or Windows Vista, read-only access to these drives can be achieved through a program called BitLocker To Go Reader, if FAT16, FAT32 or exFAT filesystems are used. [15]
EFS is available in all versions of Windows except the home versions (see Supported operating systems below) from Windows 2000 onwards. [2] By default, no files are encrypted, but encryption can be enabled by users on a per-file, per-directory, or per-drive basis. Some EFS settings can also be mandated via Group Policy in Windows domain ...
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...

When a computer with a self-encrypting drive is put into sleep mode, the drive is powered down, but the encryption password is retained in memory so that the drive can be quickly resumed without requesting the password. An attacker can take advantage of this to gain easier physical access to the drive, for instance, by inserting extension cables.
Windows 7 includes AVI, WAV, AAC/ADTS file media sinks to read the respective formats, [84] an MPEG-4 file source to read MP4, M4A, M4V, MP4V MOV and 3GP container formats [85] and an MPEG-4 file sink to output to MP4 format. [86] Windows 7 also includes a media source to read MPEG transport stream/BDAV MPEG-2 transport stream (M2TS, MTS, M2T ...
NTFS Streams were introduced in Windows NT 3.1, to enable Services for Macintosh (SFM) to store resource forks. Although current versions of Windows Server no longer include SFM, third-party Apple Filing Protocol (AFP) products (such as GroupLogic's ExtremeZ-IP) still use this feature of the file system.
Disk encryption is a technology which protects information by converting it into code that cannot be deciphered easily by unauthorized people or processes. Disk encryption uses disk encryption software or hardware to encrypt every bit of data that goes on a disk or disk volume.
