+1 for FreeOTFE

Is this better than TrueCrypt? I've been using TrueCrypt for years and never had any problem whatsoever.

The main advantage of FreeOTFE is that there is a container explorer (FreeOTFEExplorer) which allows to read and write in the crypted container without admin rights. Those are needed for installing the drivers.

There is a TCExplorer for TrueCrypt which does not allow to write in the container and is not working with the latests versions of TrueCrypt. To my knowledge, it is not supported anymore.
