Mounting An Encrypted Drive

If you are not using an encrypted drive (yet) you can skip this section and go immediately to )

Here is a very simple DOS batch file, Mount.BAT that you can save in your C:\SAFE.

TITLE %0 Mount an encrypted drive
if not exist X: 	"C:\Program Files\TrueCrypt\TrueCrypt.exe" /Q /LX  /V \Device\Harddisk1\Partition1
REM End

On my system, I elected to use drive X as the target for backup files.

The excellent TrueCrypt documentation told me how to mount a drive.

The only operation line in the batch file tests to see if drive X: exists.

If drive X: does NOT EXIST then the TrueCrypt command will be executed.

TrueCrypt installed itself in "C:\Program Files\TrueCrypt\TrueCrypt.exe" (note the double-quotes) so that’s where it will be found.

/Q

“Automatically perform requested actions and exit “, also known as Quiet operation. No user intervention is required. Lovely!

/LX

“Driver letter to mount the volume”. I want the encrypted drive to be mounted as drive X:, hence the letter “X”

/V \Device\Harddisk1\Partition1

“File and path name of a TrueCrypt volume to mount”.

When I run TrueCrypt and choose Select Device, a window pops up in which I can see all the devices recognised by TrueCrypt. I choose the appropriate device and key its full name in here.

When my little batch file has run, drive X: will be available to me.

In the rather lengthy screen shot above, you can see that I have executed C:\Safe\Mount.bat and that drive X: is now available to me in unencrypted form.

Waiting For The Backup Drive
