    Hi,
    I just upgraded my 2012 Mac Mini to SSD. Everything works and is amazing, BUT: When I connected my old hard disk via USB I found that I had complete access to every last shred of data, no password, no nothing — FileVault notwithstanding. What's that all about? Is the disk only protected while it's built in? And doesn't that pretty much defy the purpose of my data being safe if the computer is stolen?
    What can I do to make sure that nobody can access my new hard disk?
    Thanks a lot!

    Did you do a clean install, with no time machine restore after the install? If you used time machine, or some sort of restore at any point in time, I highly suspect the record of the password was copied into the new OS. Try to plug the drive into a friend's Mac and see if you still have access.

    If my memory serves me correctly, it won't work unless you enter the password.

    I cloned the disk to the new one with Carbon Copy! If I understand you correctly you think that my old disk is only accessible without pw when connected to my computer — to itself, essentially. I'll try that out at when I get the chance – thanks a lot!

    the password to your hard disk is stored in keychain access
    delete the keychain

    try connecting it to another mac


    the only other explanation is that if you need access to an encrypted disk for the next reboot, you need to go to terminal and run " sudo fdesetup authrestart' to put the decryption key in ram.
