Testing whole disk encryption

[Patrick Hendrick <phendrick () gmail com>]

I've recently installed the latest TrueCrypt version which does whole 
disk encryption. I have encrypted my HD on my laptop and want to verify 
that it is doing what it is saying that it's doing. So far to test I 
have used the Knoppix Insert seurity live CD and tried to mount the 
drive. Unsuccessful as I figured it should be. Then I used GParted to 
take a peek at the drive and it showed as uknown file type or 
unformatted. Anything else I can do to verify the encryption?
