Thats where it looks like eventually this DiscFerret device may help. But it's not quite all there yet. Soon maybe. It has it's own USB floppy controller into which you plug a floppy drive with a 34pin cable.

I wouldn't interpret "Dumping Project" too literally. The name comes from the MAME Dumping Project, which preserves arcade games stored in a number of formats, including ROM chips, CDs, and hard drives. So I'd say any software MESS could potentially emulate is fair game.

Does anyone have experience using Kyroflux or DiscFerret? I'm curious about what type of disks people have tried on them, and how well they've worked.

Kryoflux works excellent for me on 8", several formats. You need an extra adapter for that though. 5.25 and 3.5 should work fine.

Kryoflux is easy to use, I have one and i'm quite happy.

The only problem is that converting stream files to ipf format is still not automatic.

That said, why not use stream files right away?

I'm taking a look at DiscFerret too, but seems that it's a bit green on the software side.

Jonas, can you tell me a bit more on the 8" adapter? I have one 8" drive I'd like to try, and if it could be used for preservation, much better!

I also have a KryoFlux and it works very well. If you don't need IPF from your dumps instantly, it's okay. It'll probably not take much longer until emulators (and MESS?) support the stream files natively, or until an open source IPF converter shows up (see https://github.com/keirf/Disk-Utilities)

Regarding the 8" drives, the KryoFlux community seems to be using the one from dbit.com (see http://forum.kryoflux.com/viewtopic.php?f=3&t=689 for a discussion) with some success...

Yep, that's the one I've been using.

Thanks for the reviews. Has anyone tried disks for the Apple II family of computers? IIRC, at one point these weren't supported because they used a unique format. From the Kyroflux website, it sounds like they are supported now, though.

I also remember that people were excited for Kyroflux because it might be able to recover data from disks that were too degraded to work in the original hardware. Has anyone tried this?

so it looks like various Apple sector images are supported now (I don't have an Apple to test)

Apple II is supported but in my experience it doesn't work very well, nonprotected disks that read fine on my //c come up as full of bad sectors with the Kryoflux. It may be down to the drive I am using although it works fine with PC disks. I haven't tried recently though so they may have fixed it in software.

There is also the issue that stock PC floppy drives can't read the reverse side of Apple II disks unless you make some physical modifications to the drive.
