I've used Johnny's POC1>POC2 converter to convert my plot files. I see the warning that says that if the process is interrupted that the plot file on which it was working would become corrupted. I know for a fact (i was in the room) that this happened at least once as Microsoft was trying to help me when it rebooted my system to run updates.
I don't know which plot file(s) were being converted at that moment. Blago's miner is not throwing any errors. Is there a way to verify the integrity of a POC2 plotfile without re-plotting everything 'just to be safe'?
