If you image them with KryoFlux, you can later restore them to the original condition...

I don't have a KryoFlux.

I can't think of a scenario where I'd consider overwriting original media. The factors that prevent me from installing Office from floppy disk also remove any need I may have for a number of high quality disks.

Floppy disks are pretty much my file transfer medium of last resort at this point. If the computer is on the LAN, I'll use the LAN to get stuff on/off it. If it isn't on the LAN (or it has a blank hard disk), I'll put it on the LAN and I only need one floppy disk to do that whether its got an OS or not. And if for some reason I have a need to run a PC with no hard disk at all then I'd probably pull out the floppy drive too and just boot the machine from the LAN.

So for pretty much any floppy disk use case I have, a bunch of cheap disks of questionable quality are good enough. Plus while original disks may not be particularly valuable today, that could change in the future. Microsoft isn't making any more of them after all.

Winimage can read and write DMF floppies/images and can format a HD floppy in DMF format. I also have a bunch of original MS floppies that I will not use since there is about 100+ NOS good blank disks in boxes laying around the room ;p

I second what @davidrg said - no PC should be without LAN!

Back in the era, there were two obvious differences between real computers and toys: HDD and LAN.
The former had both, or it was easily added.
And with both HDD and LAN, the need for floppies is minimal.

I use floppies a lot, that's part of the fun for me, I always install MSDOS and Win 3.1 from floppies. I have a dedicated floppy drive to boot a memtest disk for the first test of a repaired motherboard or CPU.
Other people enjoy a CRT because it's part of the experience, I just have them out of curiosity.

Never overwrite a oem original disk 😀

Get goteks!

Second'ing the others who don't re-format original media. I keep all my original disks just as they were too. Just for myself personally, the thought of re-using them for a different purpose has never even entered into my head since it's still possible to get sealed-new-old-stock disks that are of good quality.

Also I'll add that I do still actively use floppies for my own uses with my retro PC's (transferring files, etc). It's all part of the experience. Using stuff like Gotek's or whatever else just removes part of the fun for me personally. I don't even own such an adapter. Though I also ensure all my retro PCs have LAN access too for transferring things between modern and retro machines.
