It says:

fdisk -l /dev/sdd

Disk /dev/sdd: 2000.4 GB, 2000398934016 bytes
255 heads, 63 sectors/track, 243201 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

And the first one I tried with 

fdisk -l /dev/sda

Disk /dev/sda: 2000.4 GB, 2000398934016 bytes
255 heads, 63 sectors/track, 243201 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        1216     9764864   fd  Linux raid autodetect
/dev/sda2            1216        2432     9765888   fd  Linux raid autodetect
/dev/sda3            2432        8511    48828416   fd  Linux raid autodetect
