Floppy image restoration request - images have Side 2 folder

The attached disk images don't work in Hatari. They have a tricky disk format that allows for SS drives to read part of the disk and DS drives to read the full disk (SIDE_2 folder). The contents of both sides are inaccessible in these images. I think this can be fixed by writing these images to disk on a PC and copying each disk's contents file-by-file onto a blank formatted disk using an Atari ST, and then imaging the new disk onto a PC. Could someone attempt this and post the restored images back to this thread? Thanks in advance!

[edit] Removing the attachments.

Images are bad - that's why work not in Hatari. You need to make 10 sector/track, 810 KB images. Will work in Hatari and Steem.

These were made using dd with a usb floppy drive. I don't have a working Atari ST that I can use to image these on the Atari.

Unlikely you can dump these disks with a standard USB floppy disk drive. Do you not have a PC with an internal floppy disk connector on the mother board?

Yep, that's known problem - USB can not 10 sectors/track - so you need some other way. As said, some older PC can do it - but then, still need special SW for Windows, what overrides driver limits. http://atari.8bitchip.info/floimgd.php
Don't know for Linux, probably dd is OK, just need to set proper geometry.
Searched little, it seems that no images online .
