June:
As a general rule, if you go and open your Apple System Profiler . . .
. . . COMPUTER-->(YOUR) HARD DRIVE-->APPLICATIONS-->UTILITIES-->A.S. PROFILER
. . . you can find all sorts of specific descriptive details on your SYSTEM, the various DEVICES AND VOLUMES driven by your system, plus lists of EXTENSIONS, APPLICATIONS and other goodies. You'll find version numbers which will help you understand "what's in there"! Really.
FIND will quickly detect items you have named as you're created documents, or the elements of your OS provided by Apple, but it's unlikely to find such information as the brand name of your HD.
Apple System Profiler provides all that "stuff" in a flash . . . well, almost in a flash.
