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:

lshw 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

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

Linux GUI Disk Utility
Gnome users can use the gnome-disk-utility for the following purposes:
- Get information about installed disks and its current health.
- Manage and configure disk drives.
- Manage and configure media.
- Manage and configure software RAID devices.
Type the following command or start Disk utility by visiting Applications > System Tools > Disk Utility :
$ palimpsest
smartctl Command
The smartctl command act as a control and monitor Utility for SMART disks under Linux and Unix like operating systems. Type the following command to get information about /dev/sda (SATA disk):
# smartctl -d ata -a -i /dev/sda
Sample outputs:
