You can run drive diagnostics, copy files to and from the volume, and even format the device.
In Target Disk Mode, you can access the target computer's drive with the same freedom you would have with any other disk connected over FireWire. This trick is great for fishing files off of a machine that can't boot OS X correctly, since it operates independently of the Mac's installed operating system.

So i tested to full image with the Target Disk Mode at the Source Mac. But with several test i had to find out that it is not possible to start from the dongle. Apple's article on target disk explicitly says Firewire and Thunderbolt are required for target disk mode but the excellent iMore review article says: You can transfer data at up to 5 Gpbs over USB 3.1, USB 3, or USB 2, or over ethernet with a USB adapter. Because of the workflow of the User Guide i had to start from the dongle. (The icon will look like a Y with a circle in the center.) For m test, i wanted to image a MacBook Pro 2018 encrypted with a T2 Chip and FileVault2. Once the slave Mac has finished booting up, if you've found Target Disk Mode correctly, you should see the FireWire icon appear on the target Mac's screen.
B) When it does recognize it, the Startup Disk shows the name of the drive and says it is encrypted for a few seconds and then it gets removed and added back without the encrypted text (but FileValut is off - is this the T2.

And Ive been trying to put the MBP in target disk mode and boot the iMac using that disk.Connect your target Mac to the host Mac using your 6-pin FireWire cable.First, if the Mac you want to access as your target is powered on, shut it down.Here's how you can take advantage of this capability: All you will need is a 6-pin to 6-pin IEEE 1394 - commonly known as a "FireWire" - cable. The mode still works normally as I am seeing the appropriate USB and Thunderbolt icons on the machine that I am T-Booting but the drive will not appear on any host machines. With Target Disk Mode, you can use a recent Mac to access the main internal hard disk in another recent Apple machine without having to crack a case or turn a screw. Does Target Disk Mode work with USB-C cables I support primary 2016-1017 MacBook Pros that only have USB-C connectors and I am unable to run Target Disk Mode on them. That feature is the Target Disk Mode built into the Mac firmware.
