That function isn't in any official Free42 release yet, though, it's only in the test versions of Free42 and Plus42 that are currently on my web site. Using that ...

I formatted the DM42 and put in it a backup without losing FW. With DM41X I was able to reconnect usb, then copying the folders from a ...

Re: USB connectors
I have no issues with Big Sur & DM42 and the cable I mentioned 5 postings above. With other cables with shorter plug and less secure fit I had disconnects and hence FAT trouble on Mac and Windows. I'm investigating here, if the issues are with Big Sur or also with Parallels (to run Windows and ...

Re: USB connectors
mine now is this one, and it seems to be good enough, however I had the problem also with this: FAT disk stuck, spinning wheel and so on, so I would like to understand if there are some software problems here in macOS Big Sur or other issues.

Re: USB connectors
today same problem with the DM41, as with DM42: the cable USB-c/micro is ok, but the disk stuck accessing the folder /State (with a spinning wheel), I had to force expulsion, then the calc also was stuck and I performed a pin reset, losing all.
