As Dirk sees it

Using SystemRescueCd and truecrypt from command line

This link http://m2otech.com/linux/7-troubleshooting/21-mount-ntfs-truecrypt-volume-readwrite-with-ntfs-3g

Mentions:

There are two popular ways to mount NTFS volumes on Linux systems. One is ntfsprogs, the other is ntfs-3g. They both offer similar functionality with read/write access to NTFS volumes.

If you use ntfs-3g mounting a TrueCrypt volume which is formatted as NTFS will not be done read/write by default. Only read access will be provided when mounting through the graphical interface. Solve the problem is by using command line option --filesystem to explicitly call ntfs-3g mounting option.

For example mount TrueCrypt volume /dev/sdb1 to /media/truecrypt1 will be done as follows:

truecrypt --mount /dev/sdb1 /media/truecrypt1 --filesystem=ntfs-3g

(Note that the mounting point /media/truecrypt1 must exist)

To unmount a TrueCrypt volume from command line use the --dismount or -d option:

truecrypt -d /dev/sdb1

or

truecrypt -d

but..... for me this didn't work, I also had to read this:

http://forums.debian.net/viewtopic.php?f=10&t=57474

which mentioned :

truecrypt -t -k "" --password=MYPASSWORD --protect-hidden=no
  /dev/sda1 /media/truecrypt1
and more importantly:

--mount-options=system
so I ended up using this command:

truecrypt --mount /dev/sda2 /mnt/windows --filesystem=ntfs-3g
         --mount-options=system

Which worked for me. The above lines have been written on 2 lines
so they don't trail off into my twitter feed on the right.

Whats happened to word wrap.

and why does IE squash all my lines together and firefox looks ok?
