2TB hard drives

I picked up some nice things out there today and was wondering about some hard drives I found.
they are external drives, as in they have an outer casing they sit in.
2.0TB Western Digital Caviar Green.
what do you think, would these have anything more then say a 60GB hard drive has?
what would be different? they feel heavier then normal,



but they all seem to of had a whack maybe with a hammer on the back where the board is, more like a dent so I don't think they would be worth trying to sell, see the screw on the right and the little crack?



was thinking maybe there's a component inside that might be special?

Newegg.com - Western Digital Caviar Green WD20EARX 2TB 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive

$119.99 on new egg new.

$75 should be a good price if they work

I rather try to see if they work 2tb internal drives are super nice. I know i just about filled up my first tb this year.

DONT SCRAP IT! Test it and see if it works. If it does, sell on craigslist or even ebay.

2tb hard drives of any kind, are in good demand!

To try and answer your question, I think you'll find 1 or 2 extra platters inside but being newer they might be glass platters, like Olddude was talking about awhile back.
