i have a Lexar 8GB flash drive and i want to protect it using some software i forgot it's name o anything about it ! .

The software creates 2MB (i think) partition on the drive and the rest of the drive becomes an encrypted partition (so physically the drives will have 2 partitions)

the 2MB partition is READ ONLY and has one executable file , when when launched asks for a password and unlocks the 2nd partition after mounting it .

does anybody know this software , or something similar ?

This sounds very similar to an inbuilt feature of an old usb stick I have. It essentially switches modes on the stick, so it's not something that can be installed on a drive. There may be a program that does this, but I doubt it, as Windows doesn't support multiple partitions on usb devices normally and the software would have to install a driver to mount the extra partition. – Tamschi Feb 24 '11 at 12:11

TrueCrypt is very secure disk encryption software.

Also, if you install this in Portable Mode and create a container on the stick it behaves almost exactly like the program in question. (The container is visible and the drive isn't read only though.) – Tamschi Feb 24 '11 at 12:16
    
I would recommend TrueCrypt too, but beware that you need administrator privileges in order to run it. – Specur Feb 24 '11 at 13:19
