5.25" vs 5.5" floppy disks.

KNOW THE DIFFERENCE.

A photo of a 5.25" and a 5.5" floppy disk next to each other. Despite looking very similar, they are not, as one is different.

@NanoRaptor Too many folks try to store People on their 5.25" floppies and it never ends well.

@NanoRaptor What?!?!?!? My mind is being boggled. I didn't know 5.5" floppies were a thing.

@reaply @NanoRaptor

Nonsense. One has a label that says "People", the other "Documents". 😉

Couldn't be more different, unless of course one of them was 1/4" larger than the other as well.

~/phranck :antifa:

@NanoRaptor WHAT? I never heard of the 5.5" format. 😳

@phranck @NanoRaptor International Machine Bosses launched them as part of project Deep Teal. Unfortunately they never really took off outside of public libraries and horse tracks.

As per usual, the porn industry preferring 5.25 for distribution of their steamy novels settled that format war as well.

@AngryAnt four frames of ULD video ought to be enough for anybody!

@NanoRaptor reminds me that the width difference between a 3.5 inch drive and a 2.5 inch drive is 1.3 inches

@NanoRaptor I think it should be the other way around since there are more documents than people.

Sindarina, Edge Case Detective

@NanoRaptor I both love and hate that I am almost sure that this is fake, and yet not entirely, while resisting the urge to go look it up 😂

Christian Gudrian

@NanoRaptor Be careful when labelling your floppy disks with a ball pen… 😀

INPC

@NanoRaptor I know this! One is bigger than the other!!

damon

@NanoRaptor Will my hole punch still work to double-side these?

George Haritonidis

@NanoRaptor the extra 60KB capacity sure was welcome back in those days

Chumchum Tumtum

@NanoRaptor they look nothing alike, I can't believe anyone might confuse the two

Greg Parker

@NanoRaptor TIL, I thought the big one was 140mm.

Salva

@NanoRaptor never seen a 5,5” disk 😮

Light🐧⁂

@salva_pl @NanoRaptor
Me neither, I didn't know the 5.5 inch ones even existed up until this moment. 😲

Drew Gilmore

@NanoRaptor Few will fondly remember Verbatim’s even less successful attempt at a 5.375” floppy disc.

/dev/urandom

@NanoRaptor i spent so much time looking at tiny details in this image and after seeing enough differences making it so the second floppy is not just a scaled image of the first one, i am honestly not even sure if this is fake

UPD: i noticed one detail that does make it look like the second floppy is an upscaled and heavily edited image of the first one :-p

Wolfram Rösler

@NanoRaptor I remember that getting a 5.5“ disk into a 5.25“ drive was pretty difficult. Getting it out again was a lot more difficult though.

Nini

@NanoRaptor Juuuust off enough to be deeply upsetting.

Ian Malcolm

@NanoRaptor

Regardless of size, my hand is twitching with the desire to cut another notch in the left one, so I can use it double-sided in my 1541-compatible Skai-64 floppy drive.

mORA

@NanoRaptor I had a 11,3” one labeled “Dreams”

Foone🏳️‍⚧️

@NanoRaptor I definitely need a few of these for my collection.

Maybe I can modify an 8" into one...

🔞Labrus🏳️‍⚧️

@NanoRaptor good thing the later 5.5" drives were often dual-format so you could also put your 5.25" disks in.

Solarbird :flag_cascadia:

@NanoRaptor oh wait I know this - instead of 300 or 360 RPM they're either 286 or 377 RPM.

Also, the whole two hub rings thing. Not that you can see it in that photo, of course, but that's why you needed to know. You could trash a 5.5" floppy pretty bad if you didn't.

Erica Briony.

@NanoRaptor gosh remember the good old days when you could fit more than one person on a floppy? Why these days I reckon you'd struggle to get one on a DVD.

Andre

@NanoRaptor didn’t someone once say „documents are people, my friend“?

Nicola

@NanoRaptor Technically they were not 5.5" disks, they were 14cm disks, but americans just insisted on using the non-metric measurement.

As such they were also a fraction of a mm bigger than 5.5".

Colin Chick

@NanoRaptor they're both identically different, except for the other one.

Bob K Mertz

@NanoRaptor
Clearly created by the same guy that thought it was a great idea to have only 1/8" difference between a class 1 and class 2 hitch ball for towing.

europlus :autisminf:

@NanoRaptor some faulty 5½" drives were supplied to Apple and Woz got them working with double the original capacity of the Disk ][, but he couldn’t convince Jobs to tool up new face plates.

A judicious use of a Dremmel on either side of the opening gave savvy Apple ][ users a bonus for their own use, but they tended to be shunned by their friends at disk swap parties because only about 3% of Disk ][s ended up with the 5½" drives.

They were also derided by girls for claiming “Mine is 5½"”.
