Re: Problems writing back to floppy disk

I've managed to successfully duplicate this disk and its copy protection back to floppy using Transcopy 3.0 and an option board. Central Point Software mentions in an amended document to their manual, that when one is having problems with Softguard SuperLok v3.00 copy protection make sure you disabl...

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.
Could you give me an example how to do this? Thanks.

Re: Problems writing back to floppy disk

The break is generated by the drive when the write current is removed from the heads. Some generate larger glitch, some shorter. KryoFlux, or DTC, when writing from raw files just writes the track from index to index as it has no further knowledge if a break should be made to appear somewhere else....

Re: Problems writing back to floppy disk

Interesting. So is there a way to force KF to not leave that slight break? I have the TC images converted by NRS which work on DosBox-TC. Not sure if they would help on this investigation? But all three versions and the Sideman run fine. Unfortunately I have a Deluxe option board and cant write thes...

Re: Error: Extra Data was found hidden in unused paths of the block header

Thanks David. I did read that a while back but this version looks more complete. Thanks for the link. It's now clear. That could be from the Softguard Superlok 3.0 kit copy protection and the way it was originally written to disk.

Error: Extra Data was found hidden in unused paths of the block header

Hi guys,
Could someone let me know if this is an ERROR or just the CP of a disk. I'm getting it on some Superlok CP floppies.

"Error: Extra Data was found hidden in unused paths of the block header"

Thanks,

Re: Problems writing 720kb PC booter

Thanks for the reply. Right. After reading your comments I decided to supply the power to my 3.5" floppy drive not via the adapter I got with my KF but via a PSU from a 486. I still get the "Error: Extra data was found hidden in unused paths on the block header", but I don't get it overlapping to tr...

Re: Problems writing 720kb PC booter

Im giving up on this. These floppies just don’t dump with KF. I’ll archive them with Transcopy instead. Hopefully if the dev team has time they can shed some light on this.
Thanks guys,

Re: Problems writing 720kb PC booter

The TC copy dump is not a regulary kryoflux dump! What tool did you use to create it? It looks like a perfectly alligned data fetch... (Look at the small size compared to your first dump!) BTW: It shows a modified index gap on the first track and a short sector on the last track which could be the ...
