Problem is, that it seems, I am the only one with a Windows 10 and native disk drives (USB-drive are working absolutely perfect with HD and DD). Afterwards formatted it with QPC2 (result: 2880/2880), but I could NOT copy anything to the disk, it has been always copied to WIN1_ with strange filenames (e.g.: WIN1_subdir_FLP1_filename). the disk is read and writeable with my drive. I have formatted a HD floppy on windows (copied a file to it, made a DIR command (OK), and deleted the file. Most probably only Marcel is able to help. Former (Windows) versions didn't even support native floppies (only USB floppies where working). It seems, it is not possible to access the native floppy drives (those connected to the 34 pin Shugart bus of the mainboard) on Windows 10 (v1803). From Duncan's experience, it's obvious that even those tips aren't the answer to all the have now tried nearly anything. Looks like all we can do is to follow the suggestions of RWAP and I as regards formatting, to try them out - the FORMAT command from DOS and the use of *D to 'force' DD formatting. Reading online forums, it seems that the whole topic of floppy disks is hit and miss even for PC users.

My experience has always been that from Windows 7 onward it was very hit and miss. It looks like RWAP and I have been lucky that we can use QDOS DD disks to various extents on our PC systems. I still have a lot of old program disks on DD disks which I occasionally need to access, even though most have over time been copied over to other media.

I also still get sent DD disks in the post occasionally from people who want a copy of something on my website but haven't the experience/confidence/tools to download, transfer to QL, unzip etc. The reason why I want to be able to use DD disks is that one of my QL systems only has DD disk drives and an old disk interface which does not support DD disk drives.
