How to get detailed information about the harddisk installed on a Linux server
Detailed information about the hard disk type, disk vendor etc. of the disk used on a Linux system can be aquired with the linux tool hdparm. If hdparm is not installed on your server, it can be installed with this command (on Debian and Ubuntu systems):
apt-get install hdparm
For other Linux distributions, use the software installer and search for the package name ‘hdparm’.
To get the detailed disk info, run this command
hdparm -I /dev/sda
The device /dev/sda is the first SATA disk on the server, the second disk is /dev/sdb. Replace /dev/sda in the command with the name of the device that you want to query.
