[dm-crypt] LUKS is written to a device with no partition table. Is it possible to add a partition table?

If you're going to buy one disk just for 2.8 TiB of data and plan to put 
it into your RAID array later, get a drive that matches the drives that 
are already in your RAID array (4 TB NAS HDD?).

Checking prices on Amazon for my 8 TB desktop HDD and mobile rack as a 
backup device suggestion:

- Seagate desktop HDD 8 TB $320


- StarTech mobile rack $65


So, $385+ USD for a 8 TB desktop HDD with mobile rack.

Then I discovered that Seagate makes an "Archive" HDD. This may or may 
not be the right drive for your application, depending upon your process 
and tools:

- Seagate archive HDD 8 TB $215


So, $280+ USD for 8 TB archive HDD with mobile rack.
