Essentially a great product. Secure, fast and reliable. The only drawback I can think of is that key management is a a bit of a hassle compared to the commercial products. Eg. if you want to be able to recover data for a user that has lost her password.

For those of us managing enterprise environments, TrueCrypt requires administrator rights when you insert the thumb drive into the computer. Not ideal.

Is that true even if Truecrypt is already installed on that system? –  Roy Dec 1 '09 at 20:18
    
I don't believe so. This doesn't work for me because I was looking for a solution that would run right from the USB drive for my end users who don't have admin rights on their workstations. –  GregD Dec 1 '09 at 21:12
    
Documentation confirms that once installed, a non-admin can use. truecrypt.org/docs/?s=non-admin-users –  Will M Feb 3 '10 at 18:41
    
@Will M - While it's true that you can run it without admin rights, you can only do that if TC is installed on the workstation by an admin. We were looking for a completely portable solution via thumb drives and TC will NOT run in portable mode without admin rights. –  GregD Feb 3 '10 at 20:51
    
Agree that is an unfortunate limitation on TrueCrypt. Please post back if you find an alternative without that issue! –  Will M Feb 4 '10 at 17:38

Wonderful product. I have used it for USB drives and full HD encryption and have yet to run into any frustrations.

I even recommended it earlier today on superuser.

I've never used TrueCrypt to secure an entire drive or device but I do offer one caution. I had a TrueCrypt file become corrupted and unrecoverable just one time when using the Mac version to open a 40GB file created by the Windows version. This may not have been a TrueCrypt issue though, as I had done the same a number of times previously. Still, it prevents me from repeating the exercise.
