You should be able to access the drive probably as drive 0. Try `gw seek --drive=0 40` for example.

8 is a verify error. Interesting. Is it always the same track regardless of writing to HFE or ADF?

Okay, so it's a copy with verify enabled, copies to HFE with no verify error, but the HFE is still bad anyway? Can you share an HFE image?

One thing you might want to try is v4 prerelease: https://github.com/keirf/FlashFloppy/suites/3437359731/artifacts/81480541 Use the non-debug zip file. Bear in mind it will look like v3.23 as the version number hadn't been...

And it might also be interesting to try a smaller USB drive if you have one. The larger ones don't always like small writes and can be slow on them....

I've checked both HFE images and although HxC complains about sectors which cross the index mark, the HFE images are both perfect and convert to bit-identical ADF images. I used...

The ADFs you supplied are also both bit-identical with each other, and with the ADFs I converted from your supplied HFEs.

A good way to create ADF images by the way is a device like Greaseweazle and a PC floppy drive attached to your everyday PC. This can dump good disks...

The issue with X-Copy may be that it makes assumptions that the track it wrote reads back identically: Whereas in ADF we throw away all but the sector data and...

I wouldn't do without verify. Apart from the lack of verification, it means X-Copy storms ahead copying data to the Gotek without ever checking if the Gotek is keeping up...
