Use another USB stick for variable data used by ( FreeBSD in "Protected" stick ) . I have an 8 GB one . Linux is seeing it as "Not writeable" and "Writeable" with respect to switch position , but I did not install any OS into it yet . Is there any possibility that FreeBSD can be used from such a "Write Protected" device with variable data in another USB stick device or USB HDD ? Mehmet Erol Sanliturk
