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:
