My WD10EARS (not the 2TB variant that this thread was about) looks correct:
# hdparm -I /dev/sdc | grep "Sector size"
Logical Sector size: 512 bytes
Physical Sector size: 4096 bytes
# hdparm -I /dev/sdc | grep Model
Model Number: WDC WD10EARS-22Y5B1

Don't we already waste that space with our filesystems? Ext2 cannot use
blocks smaller than 1024 Bytes, as far as I can see. And by default even
4kB are used for small filesystems (<5GB on my /).
