  The Block Device Characteristics VPD page (B1h) contains a MEDIUM ROTATION
RATE parameter, about which the SBC-3 spec says:
  0001h - non-rotating medium (e.g., solid state)
  0401h to FFFEh - nominal medium rotation rate in rpm..
  However, this VPD page is optional, and it also contains:
  0000h - medium rotation rate is not reported.
  So, you have an optional parameter in an optional VPD page.  If it is
there, it is likely accurate, but if it isn't there, you are just left to

  Is there a way (and if so, what is it) to distinguish between a (removable)
thumbstick (memory stick or card) and a (removable) HD ?
  I would like to recognize what is what.
