Serial Number of Harddisk connected through usb

Posted on


There is a dock station in which I have put a hard drive. The dock station is connected through USB, but there is no command in linux which gives me serial number of harddrive connected through USB ? Tried

  udevinfo -n <hard disk partion>
  hdparm -i  <hard disk partition>

udevinfo give some random number which is like 20 bit long but not serial number and hdparm does not give anything.


Use lshw. Example :

 ~ # lshw -c disk
       description: ATA Disk
       product: INTEL SSDSC2MH12
       physical id: 0.0.0
       bus info: scsi@4:0.0.0
       logical name: /dev/sda
       version: PPG2
       serial: LNDL107600KE110CRN
       size: 111GiB (120GB)
       capabilities: partitioned partitioned:dos
       configuration: ansiversion=5 sectorsize=512 signature=e565a8a5

The GNOME Disk Utility (palimpsest) shows a “Serial Number” for my external USB hard drive. An equivalent shell command to get this serial number would be this (for /dev/sdf):

qdbus --system org.freedesktop.UDisks /org/freedesktop/UDisks/devices/sdf org.freedesktop.UDisks.Device.DriveSerial

As you have written “<hard disk partition>” in your question, you might also be interested in this command:

$ ls -l /dev/disk/by-uuid/ | grep sdf
lrwxrwxrwx 1 root root 10 Jun  3 23:28 2CA8109FA810699A -> ../../sdf1
