How To Check Detailed Hard Drive Information in Linux

SumodirjoDIY, Open Source, Tutorial

Sometimes we need to know hard drive information detail including Model Number, Serial Number and Firmware Revision. How to do it? Check on the physical drive one by one, the information is printed on top of the hard drive. If it’s your PC on your house it’s easy, but what if it’s a server on a datacenter located in a different continent? you can use hdparm -I to do this.

If you cannot find this command, you can install it first. In Ubuntu you can use command below

$ sudo apt-get update
$ sudo apt-get install hdparm

If you are using Red Hat / CentOS / Fedora you can use command below :

# yum check-update
# yum install hdparm

Command that we have to enter to see hard drive detail:

# hdparm -IFor example, if we want to check first IDE drive (/dev/hda), we can use command below:
[root@sissy ~]# hdparm -I /dev/hda
