The Hitachi 7K60 and Hitachi 5K160  have detailed ATA specs but
neither mentions UNLOAD IMMEDIATE. The ThinkPad-branded 7K60 does
support UNLOAD IMMEDIATE  (despite not reporting the capability). So
either Hitachi's specs are unreliable or Lenovo uses patched firmware.
<sigh>

So far I couldn't find *any* laptop drive with UNLOAD IMMEDIATE in its
specs or marketing blurbs.
