Just my 50 cents on the topic, but you need to format the adf files using the format feature, for example using Ambiet (using file image control to insert a media first) or the workbench on the emulation, where the emulator already has the adf file inserted.

The result from e.g. createfile is just an empty disk like you would bought back then.

This applied of course to HDF files, too. The file is an hard drive content emulation and a computers operation system needs to format and partition them so data can be stored on them.
