You certainly have a valid point, and It's understandable If the HDD Is packaged/comes with a separate enclosure.

However If there are no detachable parts, I don't see why they'd segregate the weight.

I noticed the 4TB  comes by default in packaging that shows the item so I'll have to get it shipped in amaazon packaging, is that an issue? I worry about them remembering packaging an item in the shipping facility, paranoid I know but still :/

You're not paranoid at all.

It's always good practice to cover every angle when SEing.

In your opinion in doing wrong item method have I got it all covered? Order 4TB with Amazon packaging and order the 1TB in normal packaging (as it comes in the proper packaging by default) and then do the SE when I have them both. Have I got it all right? I don't think Amazon workers would remember putting the 4TB in different packaging as that would mean them talking to support which just isn't practical.
