Mid-2009 13-inch MacBook Pro - is there any HDD upgrade that will work?

[Flying Teapot]

I just installed the Hitachi Travelstar 500GB 7200 RPM hard drive without modification yesterday in my 13 inch mid-2009 Macbook Pro with EFI 1.7 and it's working fine so far with no beachballs.

so is this EFI firmware issue specific to the mid-2009 models? because i've been in the market for a drive capacity upgrade for some time but it holding off because of all the issues i've heard about non-stock drives. but i've got an old late-2008 5,1 ... should i still be worried?

Yes, this only affected the 2009 models.
