   I'm sitting here happily with my own Powerbook 150.  I have done
   installs on others' machines with little hitch, but not on this
   powerbook.

   APS PowerTools and other similar programs do not recognize the hard
   drive (int.  120 meg) as being valid. [...]

I'm not 100% sure but isn't the internal drive of your PB150 an *IDE*
drive?
