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.
✧✦Catherine✦✧@foone i did not realize there were 2x floppy drives!!
slaeshjag@whitequark @foone I got a 4x USB floppy drive from japan in box. It was a real quality of life upgrade.
@slaeshjag @foone which model?

Attached: 2 images How was I supposed to resist something like this? It was inevitable. It's a 4-speed floppy drive! 1474560 bytes (1.5 MB, 1.4 MiB) copied, 12.8767 s, 115 kB/s It's pretty quick!
