Wanted: USB Drive Encryption Software Recommendation

Good afternoon (as applicable):

I am looking for reputable freeware to secure my USB drive. I use it to shuttle my password locker and, while PasswordSafe is encrypted, I'd like an additional measure of protection. At the moment I am considering TrueCrypt.

Must be recognized by both Windows 7 and XP. The drive is a 32GB Patriot XPorter.

Thank you in advance,

Boz

Thanks all: Truecrypt it is!

Happy gaming,
