[plug] encyption - WARNING on TrueCrypt

[Shayne O'Neill]

I use truecrypt with just a file as the volume. Avoids letting it get
too down and dirty with the hd.

Seems to work fine, and I've been using it for about a year now with no
probs.

As it happens, last week I set up a trial TrueCtypt volume on two XP
computers, a desktop and a laptop, and everything worked as expected.

However, I have just done the same under Windows-2000 on a new external
USB2 IDE drive this morning on my main (dual boot Debian/Windows)
machine and disaster has struck in a big way!!!

The volume creation seemed to work OK under Windows-2000, and I
proceeded to copy files from an older USB2 IDE drive to the new
encrypted volume on the new drive. The copy (appears to have) finished,
then Windows spontaneously crashed and did a hard reboot. 

Now the partition table of the main system hard drive (which was not
involved in the file transfer) seems to be corrupted in a big way, and
neither Debian or Windows will boot. The Win2000 install disk can't see
an existing Win2000 partition any more, but that didn't really surprise
me :-)

What did surprise me, is that the Debian root partition also seems to be
in a bad way. I expected to just fix the boot sector, and all would be
well again. 
Not so!  I've run up Knoppix and I'm doing an fsck on the Debian root
partition at the moment, it's taking an age, and it looks totally
trashed!!

Anyone else had experience (good or bad) with TrueCrypt?
