Re: Random bad sectors when dumping an Amiga disk with Samsung SFD-321B

I just checked all the dumps with my own tool and every one of them was nice and clean. No bad sectors or misalignments visible.

The issue is most likely the HxC analyzer making a mistake with the data of those few tracks.

Re: Dealing With Weak Sectors

Writing high frequency signal would actually generate a section that is signal to the drive but blank to the rest of the system due to how the controller IC filters high frequency signals.

Re: Dealing With Weak Sectors

That kind of protection is probably not possible to write back as a direct disk copy currently as the software has no knowledge of what portion of a track is supposed to be "weak" and thus needs to be "written" using different techniques unlike standard data.

Re: How do I properly save Classic Mac floppies?

Finally took a look at the new dumps. Both Teac and Epson read those Mac disks quite nicely. Epson slightly better than Teac so Epson would be the preferred drive to dump Macintosh DD disks, tho Teac might have either some dirt in the heads or slight misalignment. And as expected the HD dumps made w...

Re: Floppy drive selector board

It is possible by modifying and installing two drivers (requiring driver signing to be disabled from Windows 8 and up) and modifying DTC.exe for the second board.

Re: How do I properly save Classic Mac floppies?

Have to look at the new dump later, but for the Epson drive jumpers: 12345678 ABCDEFGH 6-7: drive 0 7-8: drive 1 (usually the default to use) F-G: high density (not sure if the density select jumper completely overrides the software config) G-H: low density According to online info jumpers B-C and D...

Re: How do I properly save Classic Mac floppies?

From the histogram view all tracks look decent, tho it's not apparently very clear at first, but you can inspect the data more closely using the scatter plot in the GUI. http://www.softpres.org/kryoflux:ui:stream-plot Shareware systems disk actually has few bad sectors at the last tracks, visible as...

Re: A few small schematic improvements

Don't know who's responsible for the revisioning or if there's going to be more to come as the next evolution of KF has been in the planning and that would utilise a completely different hardware.

Re: Write a Mac 400/800K sector image using Kryoflux

Hey ZrX. Thanks for checking again. Yes, I used DD disks. The drive ejected them right away and showed the crossed out disk icon. Finder could not read or mount them either, but gave me the option to initialize it. That's what I did, to see if there are any errors. Usually the mac checks every sect...

Re: Thank you!

Enjoy your shiny new disk dump. :)

Dumping Amiga HD disks should work using the same parameters that were used for dumping Amiga DD disk.
