So, the theory is correct, the 2 sensors DO designate

When DSHD 3.5" floppies were just coming out, a box of 10 at Fry's would
set you back 40-50 bucks, depending on brand (Fujis were the cheapest,
ISTR). There were folks selling punch jigs to turn DS2D disks into
somewhat serviceable DSHD ones, adding the density indicator aperture to
the side opposite the write-protect aperture.
I never bothered with the fancy jigs--I'd just stack up five or so of
the DS2Ds in a little jig on my drill press and use a 1/8" brad-point
bit to make the hole. (FWIW, the disks were for short-term use only--I
don't have a single one surviving in the collection and I've never seen
any in conversion jobs that I've done, so the "solution" was a stopgap
at best).
So your use of a drill on a floppy isn't the first time. :)
A couple of questions for the group...
Did the price on the barium-ferrite DSED floppies ever reach an
affordable level? I recall paying something like $30 for the box of
3Ms that I have sitting here.
Does anyone have a Memorex 650 8" drive and media kicking around? It's
not something that you see in the wild.
