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
Tom Forsyth@foone Don't you need to factor in disk-swap time, or are you assuming at least 2 floppy drives? Although then how much time are you actually WATCHING the video if you're constantly switching disks?
@TomF I was factoring 15-30s per disk swap time
