Just waded through this entire thread, sent this via the feedback link to Apple:
{quote:title=pinkbeats wrote:}Afternoon,
I recently bought the latest MacBook Pro 15" 2.53Ghz and after it had to be repaired due to the DVD drive not working out of the box, I was made aware that the HDD was a user serviceable part. Thus before I went to collect it after it had been repaired, I ordered a 320GB 7200rpm WD Scorpio Black HDD (Model: WD3200BJKT-75F4T0) with a view to replacing the standard 250GB Hitachi HDD that came installed. After spending the best part of two days trying to install OS X (10.5.7) without success before putting the original HDD back in, I came across this thread in your own discussion forums:

So whilst I was on the brink of returning the Western Digital HDD back, it appears the issue could be to do with the EFI 1.7 firmware update. If that is the case, can you confirm if it will be remedied so that I can use the HDD drive that I purchased?
Thanks & regards.{quote}
I think it's a bit weak if their stock response is that they don't support third-party HDDS. Surely if that were the case, it would be contingent on them to specify
exactly what HDDs are compatible since it's a user serviceable part? I await the next firmware update when it comes, if as previous posters have indicated, they are working on it.
