Alice Averlong🏳️⚧️the best time to do win32 development is when microsoft's entire cloud has shit the bed
gotta pull out my visual studio 6 MSDN CD because the online stuff keeps timing out
and lets see if the internet archive has WinObj, because sysinternals is not responding
I'm just trying to read sectors off a floppy drive that's not mounted because it doesn't have a FAT12 filesystem!
surely this is an everyday occurrence in windows 11, why is this so hard?
ah-ha!

I'm benchmarking how long it takes to read a floppy disk, for my video player. test one is calling read(512) 2880 times
305 seconds, that's five minutes.
My video is 252s/floppy, so that's sub-realtime. NOT GOOD

That's speeds on a Teac FD-05PUW
a reasonable thing to do would be to adjust my video bitrate so that it stores something like 45-60s instead of 252s, since I can read one disk every 28s.
this'd get me MAXIMUM VIDEO QUALITY at the expense of increasing the video size from 12 floppies to 51-68
Greaseweazle + TEAC FD-235HF:
default settings: 97s
--revs 1: 66s
that makes sense. The USB Teac is a 2X drive, so it's running the disk at 600 RPM instead of the intended 300 RPM, and it gets roughly twice the speed.
there are 4x drives, but they're rare and I think they've mainly been used inside mavicas
I've got one but I'm not gonna build a video player that runs off a camera, that's just silly.
gloriouscow@foone there's always Floppy RAID 0
I Built a RAID of Floppy Disks. Oh no.
@gloriouscow exceptionally unreliable in my experience. a bunch of floppy drives via usb rarely works.
@foone so you're saying it does occasionally work
@foone i wonder if i can read a usb floppy from the arduino giga's host port
just need to make a simple protocol to read sectors via wifi
then you have a wireless floppy
@gloriouscow wireless floppy drive is on my todo, so I'd love to see you finish it before me (just so I don't have to do it )
@foone i know right it's just important that these things come into existence somehow
@gloriouscow I was actually thinking of (I have some PCB designs somewhere) making a stand-alone floppy reader, where you have a "READ" button on the device itself, it's got a little LCD to show you progress, and it stores them on internal memory, plus serves a webpage containing a list of read images
@foone thats better than my idea of making a floppy drive that holds the disk still and spins the jacket
