Re: New KryoFlux board worked then doesn't, sort of?

Quick info re naming scheme... there are 0-x cylinders (usually 0-39, 0-79; most drives can address and read a few more, but the standard is 40 or 80 (counting from 0-39 and 0-79)). A cylinder has one or two sides (if e.g. the drive has dual heads). A track is one side of a cylinder, so a disk that ...

Re: How to see which tracks contain data?

That isn't perfectly correct. If KF knows about the encoding of the data, it will of course display errors when creating the image. However, the file allocation table (FAT) is within this encoding, so yes, KF does not know about the whereabouts of a particular file. The FAT itself isn't that complic...

Re: G64 demo "Bounty Bob Strikes Back" problems.

This game not working is an alignment problem - so either your disk is not empty before your write to it ("degaussing"), your PC drive for writing is not perfectly aligned or the drive on the C64's side is not not aligned. This is one of the most troubling protections and was chosen on purpose.

Re: Oh dear, did I fry my KryoFlux?

Just in case anyone wonders: These connectors were placed for power users who might have very special needs and are willing to sacrifice the board (if anything goes wrong) because of that special need. E.g. 8" drives might need special care power rail - wise. Keep in mind you are using steampunk tec...

Re: Oh dear, did I fry my KryoFlux?

Thanks for feedback. I really think it's explained in detail. Quickstart shows how to set it up and clearly warns to read the main manual before attaching anything differently. On page 4 there are several key facts: (3) MOLEX power connector: KryoFlux is a fully bus powered device. Therefore no exte...

Re: Problems writing back to floppy disk

Yes, you write e.g. a Python script, and rotate the raw data within the track and as a result place the write splice where you think it should be.

Re: Problems writing back to floppy disk

You could also re-format the raw streams to juggle the data in the track as needed to move the write splice to the write splice. Since we generate one file for each track, it should be easy to re-format and exchange.

Re: Oh dear, did I fry my KryoFlux?

No, something must have gone wrong. We have used dozens of these drives. If the driver IC gets hot, it's likely it's burned. No part of the device should get hot, it was designed in a way it does not need cooling etc. It's very clearly stated in the manual (I believe in bold red letters) that routin...

Re: "could not communicate with kryoflux hardware"

I suspect there's a problem with the underlying install of DTC.

What happens if you open a terminal and execute

DTC -c2

Re: I have a KryoFlux ... now what?

We recommend capturing both streams, e.g. preservation and a decoded one. This will give you the option to go back to the preservation stream and re-feed it into the system like a real disk.
