From http://community.wd.com/t5/External-Drives-for-PC/Exceeding-2Tb-limit-questions/m-p/234694#M7754 it seems that the 3TB My Book supports 512e emulation.
However, I cannot find any confirmation of 512e support for 4 TB external hard drives. Can someone confirm that WD has any 4TB hard drives with 512e emulation support? If so, which ones?
Thanks
Minh.
