Yes, SATA drives are (usually) mapped to /dev/sd* devices.  Note that IDE 
drives can also be mapped to /dev/sd* devices as well, which is the default 
for systems like Ubuntu, I believe.

Note that the command above runs the fdisk program, which lets you type in 
fdisk commands, so it does not give the partition information immediately.  
You will get a prompt such as "Command (m for help):" where you can type "p" 
to print the partition table (like above) and then "q" to exit fdisk.
