/*
* This attempts to detect whether a drive is an USB HDD or an USB Flash Drive (UFD).
* A positive score means that we think it's an USB HDD, zero or negative means that
* we think it's an UFD.
*
* This is done so that, if someone already has an USB HDD plugged in (say as a
* backup drive) and plugs an UFD we *try* to do what we can to avoid them formatting
* that drive by mistake.
* However, because there is no foolproof (let alone easy) way to differentiate UFDs
* from HDDs, thanks to every manufacturer, Microsoft, and their mothers, making it
* exceedingly troublesome to find what type of hardware we are actually accessing,
* you are expected to pay heed to the following:
*
* WARNING: NO PROMISE IS MADE ABOUT THIS ALGORITHM BEING ABLE TO CORRECTLY
* DIFFERENTIATE AN USB HDD FROM AN USB FLASH DRIVE. MOREOVER, YOU ARE REMINDED THAT
* THE LICENSE OF THIS APPLICATION MAKES NO PROMISE ABOUT AVOIDING DATA LOSS EITHER
* (PROVIDED "AS IS").
* THUS, IF DATA LOSS IS INCURRED DUE TO THIS, OR ANY OTHER PART OF THIS APPLICATION,
* NOT BEHAVING IN THE MANNER YOU EXPECTED, THE RESPONSIBILITY IS ENTIRELY ON YOU!
*
* What you have below, then, is our *current best guess* at differentiating UFDs
* from HDDs. But short of a crystal ball, this remains just a guess, which may be
* way off mark. Still, you are also reminded that Rufus does produce PROMINENT
* warnings before you format a drive, and also provides extensive info about the
* drive (from the tooltips and the log) => PAY ATTENTION TO THESE OR PAY THE PRICE!
*
* But let me just elaborate further on why differentiating UFDs from HDDs is not as
* 'simple' as it seems:
* - many USB flash drives manufacturer will present UFDs as non-removable, which used
* to be reserved for HDDs => we can't use that as differentiator.
* - some UFDs (SanDisk Extreme) have added S.M.A.R.T. support, which also used to be
* reserved for HDDs => can't use that either
* - even if S.M.A.R.T. was enough, not all USB->IDE or USB->SATA bridges support ATA
* passthrough, which is required S.M.A.R.T. data, and each manufacturer of an
* USB<->(S)ATA bridge seem to have their own method of implementing passthrough.
* - SSDs have also changed the deal completely, as you can get something that looks
* like Flash but that is really an HDD.
* - Some manufacturers (eg. verbatim) provide both USB Flash Drives and USB HDDs, so
* we can't exactly use the VID to say for sure what we're looking at.
* - Finally, Microsoft is absolutely no help either (which is kind of understandable
* from the above) => there is no magic API we can query that will tell us what we're
* really looking at.
