1. It works good,but .... the handling could be better. You MUST boot from another drive for encrypt or decrypt the drive. The problem: The software can´t unmount the partition of a drive from where you booted. Perhaps it´s a problem of the OS?

2. The Software can´t encrypt the bootdrive. I´m not lucky about that. I think,the most users have the most software installed on the bootdrive. What we need is a little bootstrap loader in the Bootsektors, like OpenFirmware, with password protection BEFORE the OS starts!

3. A little App for the Startup-Folder with a password dialog would be fine. Okay,i could start with the Cipherdisk.app,but i will not encrypt/decrypt every startup.
A little box with password dialog would be enough. Better would be to use the Startup-Userdialog of OSX to use for both, access authentication for Computer and Cipherdisks. It´s not userfriendly to type 2 passwords on every start of the computer.

4. The dialog boxes of Cipherdisk can´t handle the Return key. I must click on it.

So, i give you 3 stars for this nice program today. With the listed features above i would give 5 stars later...
