High all, so the perfectionist in me wants to swap out the 5.25" floppy drive in my Windows 98 build because the current drive is that horrendously ugly tan/lightbrown color, and it is clashing with the perfectly color matched CD-Rom, DVD-Rom, and LS-120 SuperDrive in my brand new EverCase Full Size Horizontal Beige case. 🤣.

Anyway, I have been looking for Teac FD-55BR drives because the color is correct, they are comparatively new, and they are 360K. However, I recently came across a site which claims that the FD-55BR is 360k but is 48tpi 80 track. (https://retrocmp.de/fdd/teac/fd55_i.htm) This seems odd to me because I was under the impression that 360k drives were 48tpi 40 track while 1.2mb drives were 96tpi 80 track. However this site is claiming that the FD-55BR is some bastardized amalgamation (haha perfect) of a 360k and 1.2mb drive.

In the end the only thing that matters is, will most random 360k drives be able to read floppies written by the FD-55BR? What is the important determining factor for 360k drive readability - TPI? # of tracks? Both?

Thanks for your help!

Just paint the current 1.2meg fdds front fascia to the color you desire. I recently got color matched a can of beige touch up paint to tidy up a few old steel cases for $nz41. Enough paint to cover a car door panel twice.

There's a glitch in the matrix.

Of course, as always, I'm open to correction...😉

Sounds like a quad density 720kb 5.25 floppy, not a 360.

I always thought those were fully 360kb compatible but maybe my memory is foggy.

Needed a drvprm setting to make one work in an XT @ 720k

Looking further I think the site you are referencing just fat fingered the spec

"48tpi 80 track" would result in disk media (slightly) larger than an 8" disk - 8" disks are 77 track @ 48tpi

a 720kB 5.25" disk is 80 tracks 96tpi, and thus is no more compatible with 40 track disks than a 1.2MB drive is

only difference between 720kB and 1.2MB 5.25" is the data rate, track density is identical

FD-55BR is double-sided, 40 tracks/side = 80 tracks total
In other words, a completely normal 360 KB drive.
