You have a typo in the model numbers. Am I correct in assuming that the WD20EARS-60MVWB0 is the one that reports a 4KB physical sector size?
I suspect that the difference is in the 512-byte information block that the drives return in response to an ATA Identify Device command. These data should be accessible via the Text Copy function in CrystalDiskInfo. Hopefully this will tell us whether each drive is reporting 4KB or 512-byte LBA sizes.

Go to Edit → Copy. This will copy the disk information to the clipboard. Then open up NotePad or whichever word processor ships with your version of Windows, and choose Edit → Paste (or Ctrl-V) to input the clipboard data, or simply paste the data into your next post.
BTW, you could also redirect your FSUTIL output to a text file as follows:
fsutil fsinfo ntfsinfo d: > 60MVWB0.txt
