Making floppy images

Hey all, I just ordered a USB floppy drive in hopes to archive some old floppies I have (hopefully they still work). Does anyone have tops on how to best make images of them? What's the best software to use? Both windows and mac software.

One (major?) limitation is that you will not be able to image SS 400K or DD 800K Macintosh floppy media, as these are not supported. For Mac images the floppies must be HD 1.44MB, only.

That said. If you have a Mac that's capable of booting native into Mac OS 9.2.2 or earlier, then Disk Copy 4.2 or 6.3 is a good choice.

On Windows, the older Basilisk II (build 142) emulator has excellent built-in Mac floppy disk support. It must be build 142, the newer JIT versions are not up to it's level of Macintosh emulation.

Under Mac OS 9.2.2, are SCSI drives for SS 400K or DD 800K floppies an option if we use a SCSI-to-USB adapter? Asking out of curiosity...

No, not if it is interfaced to a USB floppy drive. For 800k disks you would need a beige G3 or earlier with a built-in floppy disk drive. For 400k I think the requirement would be a Macintosh capable of running Mac OS 7.6.1 or earlier and a suitable drive, either internal or a Macintosh external floppy disk drive (connected to a Macintosh serial disk drive port).

[Edit:] Or do you mean a SCSI floppy disk drive to USB adapter? I couldn't say only that I've never seen one. The common external floppy disk drives before USB were meant for the Macintosh disk drive port (not SCSI).

Yes, exactly that: a SCSI floppy disk drive, but with a USB adapter to attach it to newer PPC Macs.
But ah, I see, somehow I figured there would have been SCSI floppy disk drives that could read 400k / 800k disks, but that was completely a blind guess on my part. I have never seen one, either, but I had somehow assumed they might have been a thing. But I guess not.

No, Disk Copy 4.2 uses its own Sony disk driver and accesses the hardware directly. Any disk drive mechanism that can read double-sided Macintosh 800K disks can also read single-sided Macintosh 400K disks.

If you have a Mac with a SuperDrive, then you can image any disk that the SuperDrive hardware can read, which is all Macintosh 3.5" formats, ProDOS, IBM 720K, and Apple Lisa 3.5" format.

Whether or not the Macintosh OS can mount the disk does not matter, so long as you're using Disk Copy 4.2!

I have imaged dozens of 400K MFS disks using a desktop G3 running Mac OS 9.

Good to know, but still no use for the OP with only a USB floppy disk drive (if he has 400 - 800k disks in his collection).

So what? You're the one who started talking about 400K disks in the post that I quoted. Was that any use to the OP either?

That is incorrect. They were 1st mentioned by me, in the post directly responding to the OP's post regarding USB floppy drives. You were responding to a comment I had made in response to a 3rd person's totally different subject matter, and the topic headed south.

Fascinating to know!

The only option to convert 400/800k floppies is using the kryoflux

I've no idea yet whether AppleSauce would read 400k especially.

AppleSauce has read/write support for 400k disks, both MFS and HFS.
