    Hi, I would really need your advice here.
    My external HDD was stolen and I would like to find its UUID, which is hopefully stored somewhere on my MacBook Pro (OS X 10.11.1).

    I used it with Time Machine for backups. If I go to Preferences -> Time Machine -> Select Disk... I can still see there the name of my HDD and it's size. Is it possible to find some more information about it (e.g. UUID)?

    I was also trying to find information about recently connected USB devices in system.log but with no result.

    Any advice would be greatly appreciated. Thank you!

    1. Open Terminal.
    2. Enter the following:

      defaults read /Library/Preferences/ Destinations

    Search for the text "DestinationUUIDs" to find the UUID of your backup volume.

    What Richard2 said.

    I know if encrypted, and tell Keychain to remember password, the disk does show up in Keychain. Since not at my Mac right now, can't recall if other (read: non-encrypted) show in Keychain.

    ADD: Back at the Mac, Keychain only remembers encrypted drives, it seems. Don't see any other drives listed.
