So, I have a lot of hard drives lying around that I occasionally move from office to office and need effective way to store them in the meantime. I’ve tried a couple of different solutions, none of which worked very well, until running across Silicone Forensics’ Hard Drive Transporter. As you can see, on the outside this is a softshell case that has a window on the back for inserting a label:
On the inside, there’s a foam insert that snugly fits and protects a 3.5″ hard drive. Alternative inserts are available for 2.5″ and 1.8″ drives as well. These things can be had for $7.95/each, so they’re also a relatively cheap solution for moving or storing hard drives so that they have some protection.
