I taught people to do Ctrl-Alt-Del and wait for

Still risky with SMARTDRV's write-cacheing!
Most people had been taught that on exiting their "productivity software"
to wait until they got the4 DOS prompt b3efore shutting off. THAT was
the disaster. Many didn't even realize that they should watch the lights
on the drives! Yes. MS-DOS had NO shutdown procedure at all. Even
when hard disk
arrived (DOS 2.00), "PARK" programs were third party! (could be done in a
few dozen bytes) IBM had a park program on their DIAGNOSTICS DISK, but
MICROS~1 never pro0vided one. Q: Does shutdown on Windoze9x park the
heads? properly?
The thing that bemused me, when I learned about it, was PARK programs
that ran /and then exited./
Once it quit, if it re-displayed a DOS prompt, then assuming you had
the bog-standard DOS prompt of $p$g, it displayed, say, C:\DOS> - and
that itself would cause a disk access, undoing the Park operation!
