How to check if you have new HDD installed?

[Newtype]

The 1TB HD of my late 2010 iMac 21" failed two days ago. This happened a day after noticing the SMART error in Disk Utility and months of significant lags overall. So I took it to my local authorized service provider and the guy there told me I would need to purchase a new HD (I had no AppleCare). It cost me $300 CAD.

When I get it back, I want to check if the actual new HD that I paid for is installed and not my old HD that was fixed somehow. Is there any way I could check this? Thx

Hi, I have iMac 21.5" (late 2010) and I just had its hard drive (1TB Seagate) replaced due to constant grumbling noise, lag, and it's ultimate failure. Is there any way that I could check if the new hardware is installed? Thanks!

The drive was replaced, right? Then it's new.

Turn the computer on.
Look under About this Mac.

Thanks for your replies but I think I wasn't being very clear in the OP. Its updated now.

Hard drives are cheap replaceable items.. repairing them is not practical.
it is Way way way cheaper to just replace the drive with a new one rather than fixing your old one. especially if they go through the effort of opening the computer.
