Under Consideration: Mercedes-Benz G500 4x4²

I am not aware of travel cases for internal drives. Usually you have the drive and once you have made sure you own static electricity is discharged on your body, open the computer and unplug the power cable and data cable to the HD. Then you unscrew the screws holding the drive in. Put the drive into an Anti-Static bag and then usually into a box that has foam padding on all sides to protect the drive and then tape it up to close it.  With both drives in their proper storage bags, you can then have both drives in between foam insulation for handling any dropping of the box, etc. Pack them in a box and tape shut, should then easily handle going through your carry on or checked in luggage. To ship a hard drive, you need to: Secure the hard drive in its original packaging or anti-static bag. If you don't have an anti-static bag, place the drive into a zipped freezer bag to prevent any moisture getting into the drive during transit. Sandwich the drive between foam or wrap it in bubble wrap to absorb any minor shocks. Put the hard drive in a padded shipping box. Close and seal the box. Label your package.

Either a co-pilot first time landing or something truly went wrong on the plane.

The incoming rectangular lamps on many GM cars in that era made them much more attractive.  They made a big difference. Now, as far the powerplant went, the notion of 500 cubic inches was mindboggling even during the malaise era.  If you want to see someone's jaw drop, tell a European that their engines have 8200 cc or 8.2 liters.  For those who aren't driving the occasional Mustang or Camaro you see, they freak out at anything over 2,500 or 3,000 cc.

Thank you for the response. I want to reinstall them into the computers, especially the "newer" one.  The old one has been a real champ.   The reason for not leaving them in the desktop is that the basic tower might have to be transported ... and not by me.  That means it will be out of my possession for a while.  Since the HDs would be traveling with me, they'll have to get scanned through airport security a time or two.  I'm guessing that shouldn't mess with the data.   I've already backed up the C drive on several large 1 TB portable hard drives.  I don't want to touch the basic functions and files on the computers since I don't know how that all works.  I stay away from the drives and files I am not familiar with. I tend to donate other things to charity.   I did give the Regal I once owned to charity.   A good friend told me that, about a month or two later, he saw it being driven around the city by its new owner and we had a good laugh. This is what I want to do.  I'm just trying to figure out if the guy or gal at Office Depot can size a case based on looking up the unit and the HD in it.  Any ideas on that part?  Or should I do that and approximate the size and weight of the part to get the cases?

I'm wondering about a lot of things related to this.  I am sure that, sadly, the passengers inside were jolted.  This is way different from a rough landing. Why was it even necessary to do it?  What was going on at the airport property at that time?  How does one even pull this off?  I've seen some vids of where they barely touch and then go off again, but this one looks way more complicated.
