Worried about falling damage Seagate internal HDD.

So my friend had an old internal 500 gb Seagate Barracuda 7200.12 he was getting rid of so he gave it to me but to get it he had to leave it on a chair at his house and when I got to it the dogs had pulled the bag it was in off the chair. There doesn't seem to be any damage to it physically, however it fell about 2.5-3 feet onto solid concrete what is the likelyhood that it is broken?
