I recently was given a small USB flash drive as an advertising gimmick. When I plug it in, only one drive appears: a CD drive with 42kb used (just an autorun.inf file which launches the manufacturer's website). I know U3 drives also appear as CD drives...

I've been given a cheap, brandless 2GB flash drive. As I have a bigger flash drive, I have decided to use it for testing flash technology robustness.
I plan to write 1's all over the drive, check for correctness, write 0's, check and so on. I'll log...

Some experiment I did with hard drive read/write speed was 10MB/s write and 40MB/s read, and with a USB Flash drive, it can be 5MB/s write and 10MB/s read.

Other programs are: Take Away USB-File encryption and Challenger.
As the Travelling Tech Guy mentioned, try TrueCrypt.
Or in Windows 7, try BitLocker To GO.
Try TrueCrypt - been using it for a year now .
