New SSD Fitted but Disk Utility Still Showing Old Disk My 2013 Mac Mini with 1 TB Fusion drive was starting to run really slowly.  I got a brand new 1 TB SSD fitted and am trying to restore from Time Machine, now.  The restore can see the Time Machine drive no problem, but when it goes forward to choose a destination disk, there is no disk indicated.

So I restart the restore process, and this time go into disk utility.  What's strange is that I can see the Samsung SSD, but also the original Macintosh HD.  I know that it's not there, as I have it sitting next to me (and besides.. can Minis have more than one internal drive?).  

So I guess what I need to do is to remove the "ghost" disk from Disk Utility and then prepare the SSD as "Macintosh HD" to accept my restore.

Can someone tell me how I do this?
The problem you are experiencing is because you only replaced the 1TB spinning portion of the Fusion drive; the 128GB SSD is still there with the boot partition on it.

You've confirmed this when you said that you can see both the Samsung SSD and the original HD.  What you need to do now is wipe both and create a new Fusion drive to combine the 128GB SSD and the 1TB SSD into one CoreStorage volume.

I've detailed these steps in this post on how to do this.  Since you've got everything backed up with Time Machine and are using it for recovery, you should have no problems migrating your data over.
