For the 128 cpm 71 and 41 disks they're in GCR by default. The 128 can read MFM com disks but by default it's GCR. If I remember right the directory information starts on track 1 instead of 18. I forget how the user spaces are done. Some disks have both track 18 and 1 populated for e.g. booting .

I don't think the CP/M disk structure is too complicated. However, if like the ones in your zip file, it uses a REL file then I won't be able to (easily) support it. In such cases I think you could probably find the CP/M directory sectors using a regular Hex Editor/Viewer. CBM-Transfer has a hex viewer, which has options to view in a more cbm-friendly format. Or, for windows I recommend the "HxD" editor.

Therefore quite some lack of knowledge. Please, bear with it :) Three question: - I more or less always thought that C128 CP/M disks were a mix of Commodore's GCR format and one or another MFM format. But the first disk I tried to create an image of turned out fine. Second disk, a CP/M boot disk: fine as well. third disk, another boot disk: nope. But as D64 it turned out fine as well. The question: what is normal? - Is there a quick way to find out whether I'm dealing with a D64 or a D71? I know tell the program to treat the disk as a D71. It first reads track 1 and then 36. If that goes wrong I know enough. But the time consuming part is Ctrl-C and resetting the ZF by removing and reinserting the USB plug. - Opencbm provides the tools for displaying the directory. But not for CP/M disk AFAIk. Neither CbmXfer. Unless I overlooked something. I have run and still run in various CP/M disks were the text on the labels faded away. Is there a tool to see their director?
