From the Disk Utility
GUI I can pick a physical disk and then click info and I get a Media name
of ST325062 4NS Media
(this happens to be disk4)
From the command line I can do diskutil info disk4
and it gives me the 4NS
but not the ST325062
(or the Media
but that might not be different between disks).
Can I get the ST325062
from the command line. It appears the full model number for the disk is ST3250624NS
