Linux comes with various commands to find out information about your hard drive. I recommend hdparm command which provides a command line interface to various hard disk ioctls supported by the stock Linux ATA/IDE device driver subsystem. This command read / request identification information such as disk size, description and much more directly from the drive, which is displayed in a new expanded format.
hdparm Command
Open the terminal and type the following command to find information about /dev/sda:
# hdparm -I /dev/sda
OR
$ sudo hdparm -I /dev/sda
Sample outputs:
/dev/sda:

Checksum: correctlshw Command
You need to install lshw command using apt-get or yum command. To display all disks and storage controllers in the system, enter:
# lshw -class disk -class storage
Sample outputs:

Find Out Disks Name Only
The following command will quickly list installed disks including CD/DVD/BD drivers:
# lshw -short -C disk
Sample outputs:
