I've recently brought a new Seagate 7200.12 1TB drive for my new gaming computer.

When it's in use (Activity) I get a NOISE like this but much louder:

Should I send it back to eBuyer under it being faulty?

It passes the short tests in the SeaTools software.I did not click on your link, but if the drive is making any unusual noise at all then yes, exchange it.Well, the noise it makes is like the noise the old Windows 95 era drives used to make, that crunching sort of sound.

I was just wondering if it was normal for a 7200.12 1TB, considering the 250GB 7200.10 in my HP is virtually silent.Did the old drive sound like that? Hard drives should not make any such sound.That doesn't sound right. My HDD doesn't sound like that (Western Digital 1Tb drive). As you bought it from ebuyer I WOULD send it back to be on the safe side. Nearly everything that I have ever bought from them has broken prematurely, but that's just my personal experience.If you're talking about the drive in my PREVIOUS HP computer, then it's barely audible, you could just hear when it's reading/writing but it wasn't noticeable.

The new PC is a new build, the drive is loud and very noticeable.

I'll be returning the drive back to eBuyer and getting a Samsung F3 instead.

EDIT: Also to add, the hard drive does also vibrate quite a bit when it's making the noise.
