Linux: Find out HDD serial number
posted on 2015-02-17 15:30:39

To find out the serial number of your harddisk, look up your /dev/sdX name via lsblk:

[sjas@ctr-014 ~]% lsblk -i
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 111.8G  0 disk 
|-sda1   8:1    0   108G  0 part /
`-sda2   8:2    0   3.8G  0 part [SWAP]
sr0     11:0    1  58.1M  0 rom

The device here is /dev/sda, as it contains my root partition as can be seen from the mountpoint information.

The -i flag is for ascii-output mode. That way copy pasting works better.

Then hdparm -i will give you the needed information:

[sjas@ctr-014 ~]% sudo hdparm -i /dev/sda

/dev/sda:
