In a couple of hours I managed to recover a huge part of data from an erased #floppy .
I made flux copy and loaded it to HxceFloppyEmulator, those are the first two images.
I managed to recover a lot of data with the software RecoveryWhiskers that I am writing.
I found some data that looks like a German MS-DOS 6 boot disk with Doublespace.
The file system data was properly blanked before it was erased (it's all blank data, I can verify from the flux view).
The way I recovered data is to slow down the the disk manually. I am baffled myself how well that worked.
