There are many tools to get hard drive information such as smartctl, hdparm, hwinfo… In this article, i will use hdparm command which provides a command line interface to various hard disk ioctls supported by the stock Linux ATA/IDE device driver subsystem.

hdparm read information such as model number, serial number, device size and much more directly from the drive. Login as root and type the following command

# hdparm -I /dev/sda

Sample output

/dev/sda:
