Seagate Backup Plus 4tb External Drive Disassembly

I picked up a few of Seagate Backup Plus 4tb drives at Walmart for an incredible price the other day.  My plan is to replace the 2tb drives in my fileserver so I needed to remove the case.  I first did some testing to make sure it wasn’t DOA before I started to take it apart.

It turned out to be very easy — the cover is held on with just a few clips that are easy to undo.  I managed to get it out with no damage at all.  The case is still fully usable if I choose in the future.

What is the drive inside?  Its Seagates standard ST4000DM000 consumer desktop drive.  

Check out the images below for instructions on how to remove the drive.
