Holy cow, I wrote a book!
I think the behavior is more petulant than finicky,
but finicky is alliterative.
Back in the days of Windows 95, I was talking with the
person responsible for, among other things, the floppy disk driver,
and I learned about a particular driver hack that was needed
to work around a flaw in a very common motherboard chipset.
Apparently the floppy disk controller in this chipset was
very picky about how you talked to it.
If the very first command it receives after power-on
is a read request,
and there is no disk in the drive,
the controller chip hangs unrecoverably.
Issuing a reset to the chip has no effect.
You have to power-cycle the machine and try again.
