[RndTbl] Linux 4K drive formatting

So... I picked up my lovely new WD Red 3 TB drives today and installed them
in my home server.

Now what? :-)  Specifically, I'm running Ubuntu Server 10.04 LTS
(2.6.32-45-server #102-Ubuntu SMP Wed Jan 2 22:53:00 UTC 2013 x86_64
GNU/Linux), and I'm wondering if I should upgrade to Precise before I do
anything with the drives, or use them as-is. I know I should align the
partitions at (at least) 4 KB boundaries, and 10.04 by default uses 1 MB
alignment, so I should be okay there.

Should I worry that the drive reports
fdisk -l /dev/sdc

Disk /dev/sdc: 2199.0 GB, 2199023254528 bytes
255 heads, 63 sectors/track, 267349 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

...instead of 3 TB, and thinks the sector and I/O size is 512 bytes?

Advice, please!
