Re: Read and write back image

Could you post the image you created? It looks like you saved it as a flux stream file. It is not always possible to write back a stream file as-is. Reading a stream file saves any "noise" created by damage or the normal operation of the disk itself. Writing a stream file as-is will write all that n...

Re: Cable does not match Pin1 on floppy drive

This happens more than you might think. Drives can either have the notch backwards or have no notch at all. If you plan to flip between multiple floppy drives, it is best to have a cable with no polarization notch.

Re: How to stop DTC trying to write at track82 when using a 40track drive and image?

Perhaps the disk was previously formatted with a "dynamic" disk formatter that would create more usable space by adding extra sectors and using extra tracks. If such a disk were later re-formatted as 360k, anything after track 39 (40th track counting from zero) would still be left. Banging the head ...

Re: How to stop DTC trying to write at track82 when using a 40track drive and image?

It tries to write its whatever on the first "unformatted" track. But if track 40 and 41 already appear "formatted" then it assumes you are really using an 80 track drive/image, and craps itself. If you know for sure that these tracks do not contain data, you can delete them. It is possible for syste...

Re: IBM PC 360kb disks: what is best 40track or 80track drive?

Copy protected IBM PC titles are usually quite simple to copy with the Kryoflux. Since you know this is a 360k disk, I also recommend using a 360k drive. If there are errors reading the non-protected data then sometimes trying a 1.2mb drive may yield different results. 1: Create a "preservation dump...

Aw, how cute. Someone who still thinks modern electronics should do what the user wants, not what the corporate overlord wants.

Re: IBM PC disk-based copy protection schemes and games

Ok, here is a more complete list of known copy protected productivity application titles based on what is archived on Winworld. Something to keep in mind, however, is that much copy protected application software simply has not been archived. It is also not always clear if some early titles were cop...

Re: Need advice on how to recover 5.25" floppy

"C:\path\01.0.raw" -e81 -d0 -dd1 -w"

It could be that you confused things by not exporting with a full filename. Typically when I export from HxC to KF raw, I export with the file name "track" so I get track00.0.raw, track00.1.raw, track01.0.raw, etc, the same as the KF GUI.

Re: IBM PC disk-based copy protection schemes and games

is Transcopy really a worthy opponent to KF and SCP? I know it's obsolete and poorly documented, but at the end of the day, I noticed people with a vast expertise in this area eventually end up being in favor of Copy II PC Deluxe / Transcopy. One of the catchy pros is compact size, but I know nothi...

Re: IBM PC disk-based copy protection schemes and games

Could you name any specific ones? One that comes to mind is VTERM II because it was so simplistic. All they did was write a compleatly normal format to the 41st track. The program checks for it and refuses to start if it is not present. Some other protected titles are in the "IBM Personally Develop...
