Hello Mostaf, there have been already some suggestions. But to find the right solution, you have to say what level of isolation of those two systems you need. - is it just to prevent unprivileged users from accessing the other drive? - then umount and removal from fstab is probably enough - is it to prevent root from reading the other drive? - then you must encrypt - is it to prevent root from erasing the oter drive? - then you must physically remove it each time -- Best Regards Vladislav Kurz
