What exactly is the question? If all you are interested in is some basic info about your hard drive, just run

Code:

fdisk -l

Note that's a lowercase "L". Good luck with it

Sorry - I'm still confused by "WWN world wide number". Do you mean the serial number, or the manufacturer's part number, or something else? My apologies but I am just not familiar with this term (when I hear "world wide number" I'm thinking "IP address"), but hopefully others have.

I'm also not sure exactly what you want, but if you need some info about the disk you could try hdparm:

Code:

hdparm -I /dev/sda
