I bought a Seagate Expansion Media 2 TB and formatted it with Mac OS Extended (Journaled). All went well until I enabled Time Machine. I encrypted my backups (so, the drive) and now when I eject the drive the LED on it is still on, and the plates inside it are still moving. When I disconnect the cable, it makes the exact sound as if it's force disconnected. Can you help me, please?

Best Answer
You can try to eject it via Terminal.app. Go to Spotlight and search for Terminal. It should be the first option. In the interface first type in
diskutil list
. You should get a list that looks a little like thisNow this part is completely in your hands. You have to identify which of those disks is the one that you are having problems ejecting. If you find this tough, you may ask me and I'll tell you which one it is.
After you have obtained your disk's identifier (column on the extreme right) you have to unmount the logical volume, followed by the physical disk. Therefore first unmount the logical volume by running
Over here you need to replace the "*" with your identifier. The logical volume is the one the looks like this: disk2 <-- This is an example, your's may be called something else.
Then you need to unmount the the physical disk by running the same command
But this time the identifier will look something like this: disk2s1 <-- This is an example, your's may be called something else. Unmount all the physical disks in your specified drive.
and then finally run
Her you have to put your own disk's name. You can see this on the left column of the terminal output.
