When the user has permanently encrypted volume, BestCrypt Volume Encryption software transparently decrypts all the data from the volume if it is opened for access. In terms of BestCrypt Volume Encryption software, encrypted volume is mounted when it is opened for access and volume is dismounted if the software does not transparently decrypt it and access to plain data is impossible.
To mount encrypted volume select the volume in main window of BestCrypt Volume Encryption and run Volume->Mount Encrypted Volume command. The software will ask you to enter passphrase for the volume. After entering a proper password BestCrypt Volume Encryption will start transparent decrypting of the volume and its data will become available for the user.
If you use Aladdin eToken device to store encryption key for the volume, the eToken must be inserted to USB port and passphrase for the eToken must be entered when BestCrypt Volume Encryption asks for the passphrase. The software does not give any hints in the Enter password window concerning eToken device because of security reasons: nobody else except legal user should know whether eToken is used for the volume or not.
To dismount encrypted volume select the volume in main window of BestCrypt Volume Encryption and run Volume->Dismount Encrypted Volume command. BestCrypt Volume Encryption will stop transparent decrypting of the volume and access to plain data from the volume will be impossible.
eToken with encryption key for volume is required only for mounting the volume. After that you can remove the eToken from USB port and continue normal work with mounted volume. The volume can be dismounted at any time by running Volume->Dismount Encrypted Volume command. The way of managing eTokens is chosen to minimize advertizing your use of eToken, besides of this, it minimizes risk of losing eToken device.
Note that BestCrypt Volume Encryption will not dismount volume if there are opened files or windows from that volume. It is necessary to keep integrity of data on the volume. For example, Windows always has some files from System/Boot volume opened. If BestCrypt allows dismounting the volume, Windows will start behave unpredictably and can damage some system data before computer will completely hang. It is more safe to hardware reset or turn off computer in extreme situations than dismount System/Boot volumes.
