Yup, same outcome, empty files

I copied 4 ADFs this time just to show it's not just the lha.run file... it creates the file, it just doesn't copy the contents...
Factory restored AmiBench (after backing up), tried different ports, different USB sticks, different microSD cards in the device... not tried different power supply... might try that in the morning... kinda running out of ideas... I do wanna know if it's just my machine...
I can probably just throw the microsd in a linux machine and copy the files that way... once I have a browser and/or ftp in AmiBench I can just get files that way...
The last update I installed reset my screen mode... so hopefully stuff I set up won't get nuked

Out of curiosity, have you tried using Dopus to do the copying? To rule out DOS issues?
