WD's Advanced Format drives are extremely new--they've only been on the market for a few months. They all have a big warning on them telling the buyer what to do for different operating systems for optimal performance. I also believe that the technology is currently only on the Caviar Green series drives that have a model number that ends in EARS, and their latest (as in, announced 4 days ago) Scorpio laptop drives.
I should also note that it isn't the 4K sectors that can create a problem, it's the 512-byte emulation on top of it that can create issues for obsolete operating systems and tools that use obsolete offsets (which, incidentally, obsolete operating systems are also the reason they have the emulation...)
