iMac HD replacement, am I expecting too much?

What would you do in this case?
The completely silent WD hard drive in my 24 inch iMac failed and Apple replaced it last week. They replaced it with a Seagate hard drive which made a continuous crunching noise and in a quiet room when my wife walked by she asked me, what is that noise? It was annoying me so I brought it back to the Apple Store and they replaced the drive again. I requested that they use the same brand (WD) as the original drive and they said they would request it but couldn’t guarantee that. After 5 days I picked it up yesterday and checked and they replaced it with the same model Seagate drive as before. I brought it home and again, the same “crunching” noise, for lack of a better description.
I guess what I’m asking is, is it unreasonable of me to expect the machine back to run silently the way it was originally? When I called again yesterday a manager came on and told me that some hard drives make noise but the point is mine did not. An analogy would be if something broke on your car that was silent, if it then made a noise after it was fixed, even though it now worked would you be happy?
They want me to bring it back a third time and listen in the back room to see if it’s not a “normal” noise. Point is the original made absolutely NO noise.

oh man... Hard Drives will ever do some noise - some more - some less - depends on the model used.

as you purchased your imac you got a "1 TB Hard Drive". Apple never wrote anywhere on the specs that you will get an "1 TB Western Digital Hard Drive".

If you order spare parts you will never know the model you get - you only know the size

I don't care if it's a WD or not as long as it's quiet. The only reason I requested a WD is because they seem to be quieter than the Seagate model Apple uses.

It's also why I'm asking if I'm expecting too much. I have to say, going from a completely silent machine to one that constantly makes noise when the the hard drive is working is distracting.

Some people are more sensitive to this than others. What apple sends is what they have to do the warranty work and that is it.

I just bought the Western Digital Caviar Black 1 TB and replaced it inside my own iMac.

This drive is only slightly audible over the din of the iMac's fan.

However, even the same model drive may sometimes be a little louder/quieter from unit to unit. Plus, Apple probably sources the best price/performance part they can find, and they probably don't worry as much about the noise as you or I would hope.

I have a Seagate 1TB in my iMac and it's very quiet. I know Ive heard some say theirs is louder but I may have lucked out. Either way, hard drives are the loudest components of a computer other than the fans. There is mechanical parts constantly moving in them that make the noise. Some may be quietjer than others but as long as they aren't making extremely loud clicking noises the drive should be working as intended. Hard drives will be audible in any other PC you buy. Once solid state drives come down in price and increase in capacity we will finally have a much more reliable and silent (no moving parts) hard drive.
