Actually they are supposed to be shipped with the compatibility
mode fixed to "on", i.e. completely transparent to the OS,
except for potentially bad performance.

What issues did you run into? Anything besides bad performance?

That is my understanding also.

Very similar to the OP. My Windows Server 2003 pc could not
see the drive whereas it could see an older 1.5TB with the 512
byte sectors.

Interesting. That should not happen, but shows that the 512 Byte
emulation is flawed in more ways than regarding performance.

BTW, that WD 1.5 TB 4K sector caviar green drive failed on me
after I wrote about 30 GB to it using my windows 7 x64 pc. So,
there may have been something else going on with it and it was
slowly dying.

Hmm, yes. Quite possible.
