Yes i can see the files on the SD card, both on the card i made with the diskimager and on the original one.
btw, the sd card i used came formatted, i will try SDFormatter tonight to be sure.
Thank's for the advice.
No problem, happy to share the help and info provided by others around here...
Just fyi, it doesn't seem like the card gets completely corrupted, I could also still read it on my pc, it just wouldn't boot the miner. I think it might be corrupting a setting in a config file or boot record somewhere or something that's not very obvious.
Good luck!
