I think I found another alternative to find the HDD serial number.
Getting the boot define is fairly easy, so is the serial number for a
ATA (IDE) hard disk. As I said, SCSI and SATA is a bit more difficult.
But there seems to be a new method that should work too - I tested it
in three very different machines, each have a different version of
Linux too. And more importantly, all without ROOT access.


Option 1)
UUID look-up can be done via /var/log/udev
This same file also gives you ALL the information about each device,
including the long and short serial number.

Option 2)
Knowing the UUID or device (eg: /dev/sda1) one can simply do a lookup
in the /dev/disk/by-id/ directory. Each file in that directory has the
following information: <bus>-<brand>-<model>-<serial#>[-<partition>]
So by simply parsing the name, you can find the serial number of the device.



Can anybody else running Linux, and preferably not Ubuntu (as I am
using Ubuntu), have a look and see if they have the same files with
information about hard drives?
