OK @Severin, you were right.
It was the WRONG adf; well as I have been in a hurry today afternoon, I was merely able to check my text file with the hand-noted infos.
This time, I had more time to retest: there's a new one now in the zone with CRC error *while* unpacking (real DMS -- Amiga).
xDMS (PC) will behave similarly to DMS on the Amiga, break and leave back an (unusable) ADF with less than 880k by far!
@Retroman: There's already a 100% version of that hint disk in TOSEC, if you're so keen on it
[DOCS dat]
