viewing the size of a drive that has no partitions

How can I see the size of a hard drive if it doesn't have any partitions yet? Linux fdisk did not tell me.

Code:

cfdisk /dev/hdX

...should tell you the size of the free space, which would be the total capacity of the hard drive, if there is no partitions on it.

Sure it does ....

Code:

fdisk -s /dev/hda

Code:

ubuntu@ubuntu:~/Desktop$ sudo fdisk -s /dev/sda
312571224
ubuntu@ubuntu:~/Desktop$

From the man pages, I get this information. Size is shown in blocks, not bytes, so how can I convert this to a human readable format such as gigabytes?

Code:

       fdisk -s PARTITION           Give partition size(s) in blocks

Here is the output of /sbin/fdisk -l.

Code:

Or you could look at the hard drive. They all state their capacity on the outside where the brand and model number are located.
