[Star Wars] Why didn't Vader just get a bunch of troops, lock down the hangar, and start disassembling the Falcon?

He knew the droids had the Death Star plans. He knew they landed on Tatooine. He knew the Falcon matched the description of the ship that blasted its way out of Tatooine. He knew that it was more than a coincidence that he found the Falcon at the remains of Alderaan. And he sensed Obi Wan just as he was standing next to the Falcon.

I can understand his reluctance to just eject the Falcon from the hangar and target a few turbolasers on it; he wouldn't be able to verify the recovery of the Death Star plans. But knowing what he knew at the time I don't understand why he didn't just call in a battalion of troops to the hangar, put the hangar on lockdown, and then start disassembling the Falcon — starting with the engines — bolt by bolt until there was nothing left but a pile of parts and the people (and plans) he was looking for.

It's not like there would be any resistance. Sure, Ben's a Jedi and Luke, Han, and Chewie have blasters, but with a ton of troops backing up Darth Vader in a shielded and locked-down hangar on board the Death Star, really how much of a chance would they have? At best Ben would stalemate Vader which would leave the three humans against a shit-ton of armed troops.

Why was Vader so cavalier about it?

That's basically what he did do. It just didn't work.  

The Falcon was kept there because of the tractor beam, Vader sent troops aboard. When the ship turned out to be empty he ordered a scanniing crew to check every part of the ship to look for the plans.   

Why would he have hundreds of stormtroopers standing there watching an empty spaceship?
