5¼" Floppy drive doing sequential & random read

An IBM PC compatible 5 1/4 inch floppy drive doing a sequential and random read of a 360KB disk.

The drive is a Mitsumi D503 360KB taken out from an Atari XF551 with the top taken off to display the drive heads, the disk is an old shareware program for the PC. Reading is done by an old DOS version of Norton Diagnostics.

mine doesn't work :'(

tried it in win 98, just says the 'drive isn't ready' or something. even tried an ISA controller board with it too.

Wonder if it's a windows thing? Gonna try my old 386 mobo to be certain.

You could have it plugged in backwards. Try reversing the data ribbon.

Random Access Dick FTW!

Man computers are so boring now a days with their SSD's and crap!

@30GB no its a shovel digging holes in the data

Back in the day when Floppies were really floppy

@MN12BIRD much rather have a reliable SSD than a fail HDD

Oooh! I have that exact same model stuck in my no name pc/at clone! Cool!

when the light stays on, it is connected backwards... i have a tip if the 3,5" drive works but not the 5,25" drive (light stays on)

try to connect the whole cable the other way round to the controller and turn it at the 3,5" drive... now it should work

i have different 3,5" floppys and i must connect some the other way round because the interfaces from them are turned upside down

[sinephase]

I tried different combinations (even though you can tell it's backward right away because the light stays on), but it turns out the P2 board just didn't like them for some reason, and a weird thing was that I had the 5 1/4 and a 3 1/2 on the same FDD cable and win 98 would try to access both at the same time, but only read the 3 1/2??

Anyway, got them working on a P1 board with the onboard FDD controller :)

Thanks for the reply BTW

whats the difference between a full size 5 1/4 inch and a half size 5 1/4 ? does either one do anything more? or does it just take up less space?

oh ok
