TrueCrypt 7.0

In July, TrueCrypt 7.0 was released which includes hardware acceleration for AES, assuming you have one of the supported Intel processors, and support for automatic mounting of encrypted volumes,

A volume can now be configured to be automatically mounted whenever its host device gets connected to the computer (provided that the correct password and/or keyfiles are supplied).  (Windows)

Note: For example, if you have a TrueCrypt container on a USB flash drive and you want to configure TrueCrypt to mount it automatically whenever you insert the USB flash drive into the USB port, follow these steps: 1. Mount the volume. 2. Right-click the mounted volume in the drive list in the main TrueCrypt window and select ‘Add to Favorites‘. 3. The Favorites Organizer window should appear. In it, enable the option ‘Mount selected volume when its host device gets connected‘ and click OK.

Also note that TrueCrypt will not prompt you for a password if you have enabled caching of the pre-boot authentication password (Settings > ‘System Encryption‘) and the volume uses the same password as the system partition/drive. The same applies to cached non-system volume passwords.

That is very cool. I use TrueCrypt for WDE on all of my laptops, and then also encrypt any Flash drives or external USB hard drives using the same passphrase I use on the WDE drives. I assume (though am not an expert on cryptography so I could be wrong) that this probably increases the risk that someone could guess or compromise my passphrase. On the other hand, I’m just trying to protect myself against snoopy passers-by and the worst case scenario where a drive or laptop is lost or stolen. I’m prepared to concede the NSA is probably going to pwn my drives if they really want to.

Enabling pre-boot authentication and then auto mounting drives that use that passphrase is a nice addition to the system.
