It's unfortunate that this drive doesn't respond to APM commands either.
Yes it is.... would be nice if they made it respond to the standard APM
command meant to configure this kind of behavior instead of creating a
proprietary command and dos utility to invoke it.  It's also a shame the
drive lies about its physical sector size and has no way to turn that
off.  Might be a nice project to reverse engineer this utility on
windows to figure out the command it sends down and add it to hdparm.

I did have a look at this a while ago (it seemed to be built with Watcom (now open-source) and a public-domain DOS extended along with an open-sourced binary-compressor - decompilation under Watcom on FreeDOS seemed possible), and it seems that Mark Lord has done a chunk more hacking on it, since there is a reference to initial support in the latest hdparm changelog - which you might want to take a look at....

Cheers,

Tim.
