Bestcrypt Volume Encryption, the whole-disk version for Windows, is
closed source. *Some but NOT all* of the source code is available for
review under the SDK (software development kit), and furthermore even
this limited source code is NOT provided under an open-source licence.
(PGP Whole Disk Encryption also makes part but NOT all of its source code
available under a restrictive licence, and it too is not open source.
Bestcrypt makes all its Linux source code available for inspection, but
NOT under an open-source licence. Further, the Linux version does NOT
provide whole disk encryption.)
Bestcrypt (and PGP) are to be commended for this, but it falls far short
of making them open-source programs. Being only "partly closed-source" is
like being only "slightly pregnant."

Bestcrypt is described as "Whole disk encryption" under the first bullet
of the Wikipedia subheading "Features" in its article on Bestcrypt.
http://en.wikipedia.org/wiki/BestCrypt
Further, even the opening defining words of the Wikipedia article on the
topic treat "full disk encryption" and "whole disk encryption" as
synonymous.

If you, who are terminologically obtuse, disagree, go argue with the
Wikipedia and stop being a nuisance here.

Asshole, you're just noise on the channel.
Go argue with Wikipedia or Bestcrypt or anyone else if you think they will
take you seriously - I won't.

What is Volume Encryption
The chapter explains why BestCrypt Volume Encryption (a line in
BestCrypt family of encryption software products) has got Volume
Encryption name. Many people may think that Volume Encryption is the
same as Partition Encryption or even Whole Disk Encryption. Sometimes
it is really so, but not always, and it is worth to learn about the
difference.
The idea of Whole Disk Encryption software is rather simple. Such
software works with physical hard drive and is intended to encrypt all
the sectors on the hard drive. In real life software usually does not
encrypt first sectors (usually 63 sectors) reserved for future use (the
latest versions of Windows can use these sectors). Whole Disk
Encryption software encrypts every hard drive on computer
independently, often with different encryption keys.
Whole Disk Encryption
Figure 1. Whole Disk Encryption
Partition Encryption software usually works on basic disks. It is a
more flexible way of encrypting data, because it allows the user to
open (enter password and get access to) different encrypted partitions
independently. Note that if a partition occupies the whole hard drive
(as partition C: on the Figure 2 below), Partition Encryption works for
the user as Whole Disk Encryption.
Partition Encryption
Figure 2. Partition Encryption
Since Windows NT time, the Windows operating system allows the user to
create multi-partition volumes. Windows can combine several partitions
(even stored on different physical hard drives) into a large single
"partition" called Volume. It is a significant step forward, at least
because such volumes allow the user to:
* create a larger single logical unit to store files (spanned
volumes);
* get more reliable way to store sensitive data (mirrored and RAID-
5 volumes);
* get higher overall performance of IO operations (striped and RAID-
5 volumes).
We call encryption software working with volumes Volume Encryption
software. Note that if Volume Encryption software encrypts a volume
consisting of a single partition, for the user it will give the same
result as Partition Encryption software. If a single partition occupies
the whole hard drive, Volume Encryption will be equal both to Whole
Disk Encryption and Partition Encryption. Encrypting of basic partition
C: on Figure 3 below illustrates that.
Volume Encryption
Figure 3. Volume Encryption
What kind of encryption is better? Partition Encryption software
usually works on basic partitions. If so, it will not be able to
recognize and work with dynamic disks where spanned, RAID-5 or other
types of volumes reside.
With Whole Disk Encryption software the user can separately encrypt all
the hard disks where volumes are stored (like HDD2, HDD3 and HDD4 on
the picture above). But every time the user administrates the hard
drives, he/she should always keep in mind what hard drives must be
opened to get some volume accessible. If some hard drive is not opened
(i.e. password not entered and transparent decrypting not started), the
filesystem structure of the volume can be damaged, since Windows may
notice that one part of the volume is consistent, but another one
contains garbage, hence, fixing is required.
Volume Encryption software works with volume as with a single portion
of data. Volume is always in one of the two definite states: if
password is not entered, the whole volume is not accessible. If the
user enters the proper password and opens the volume, all its parts,
even stored on different hard drives, become accessible. In our
opinion, working with volumes is more native both for the user and
computer, because it is a volume that stores a complete filesystem
structure and a complete tree of the user's files. As in the modern
world single volume stores data scattered on a number of physical
disks, it is more convenient and safe to manage a volume, rather than
work with every physical drive separately.

Read the BestCrypt license, it fails the open standard requirements at
every level. Among other things, the user is not allowed to modify the
code. That the source code is available for review is important, but it
is not open source.
