My guess is that the program is not handling drives as large as we both
have. I'm still waiting for any kind of response from the TrueCrypt
team.

Subject: [Bug 252939] Re: Truecrypt hidden volume size incorrect
I have exactly the same problem, the graphical client is telling me that there
is only 47.6 GB for the hidden volume.

Truecrypt hidden volume size incorrect

Bug description:
I am running Ubuntu 8.04 with all of the latest patches. The system is set up
using the LVM and the drive the system is running off of is encrypted. I have
an external 500 GB USB drive (465 GB of usable space). I have attempted to
format it with the Hidden Volume option. The results I get are strange and
probably a bug. Here are the results:
First, I choose to create a volume within a partition/device, then a
hidden truecrypt volume. I select the encryption algorithm (I have
tried AES-Twofish-Serpent, Serpent-Twofish-AES, and just AES with the
same results) and hash algorithm Whirlpool. I let the program format
the drive. 12 hours later, I am asked to copy some files to the outer
volume. I copy one small 10 kilobyte file (because the program makes me
copy something, personally I don't see why it is necessary as my intent
is to divide the disk up into two relatively equal parts for the outer
verses hidden volumes).
Next, the program calculates the largest possible hidden volume size.
Here is where things get strange. It always tells me the largest
possible size for the hidden volume is about 47.5 GB. This is on a 465
GB disk with one small 10 k file copied to it. Since I am trying to
make about a 200 GB hidden volume, I go ahead and say I want a 45 GB
hidden partition. The program finishes its work and I then start
copying lots of files to the outer volume. I can copy about 2 GB of
files before the program disables copying to the outer volume in order
to protect the hidden volume.
In other words, when creating a hidden volume of size 45 GB on a 465 GB
drive, I only get 47.5 GB of usable space for the whole drive, including
both the hidden volume and the outer volume. I have not tried to copy
files to the hidden volume to see how much it would actually let me
copy. I suspect that the 45 GB that I am typing in as the size for my
hidden volume is actually being set up as something much much larger.
When I create just a standard truecrypt volume (no hidden volume), the
drive is set up with the full 465 GB of space available.
