PS3 HDD Swapping and warranty info

Via Neogaf:

OK. Some guy claims to have asked support and got the reply "If u swap it and it stops working during the warranty period we can't support that. If u use the original HDD and it still doesn't work and the drive you tried to swap in didn't break the PS3 we will honor the warranty"
Seems like there's no problem at all here. The cant be expected to support some problem caused by a crap HDD from a different company. Just the fact they're letting us use off the shelf HDDs is makes me happy enough! I just sent an email asking support how they confirm the drive you tried to swap in didn't mess up your unit. I'll post the reply when I get it.
