Nope.

Not if you do it correctly it doesn't.

Anyone with even half a clue checks
which drive is in the case electronically.

Wrong. Those claims are pure bluff.

Not even possible because there is no way to check
if the seal has been breached without opening it.

Just because some fool claims something...

Pure bluff.

They don't when they are opened properly.

It shows up on the SMART report etc.
