Has anybody explained to Al Gore about how Windoze is the primary cause of
global warming?

Smartdrv was purely a disk cache, wasn't it?
Yes. But MICROS~1 was completely clueless what the risks were and how to
deal with them for WRITE caching (what happens if the power goes off, or a
disk error occurs before the cached stuff gets written?) > The compression was something

Therein hangs a bizarre tale of conflict and betrayal
between MICROS~1 and
Stac Electronics (billg said, "I'm having a bad day", when the court
awarded damages), and the differences between DOS 6.20, 6.21, 6.22.
Not one of his finest moments fer sure...
Ah, the good old days.
And then Windows came
along...

Two issues:
1) deliberate. The OS seems to say, "All done", and the user flips the
big red switch. With write caching, the obvious "all done" signals occur
before the work is done.
2) SMARTDRV rearranged the sequence of writes for more efficiency. When
power fails, you have a false DIRectory, even though none of the file was
actually written. Without SMARTDRV, perhaps some of the data was or
wasn't written yet, but the DIRectory will show a 0 length file, since
"closing" the file and writing the updated DIR isn't done until after all
of the data is written.
