I've spent a while tonight trying to make an image of my sd card and copy it to another, but so far have only failed. It keeps giving a few errors during the imaging while reading from the hexnail sd and at the end says it failed to write the image. Trying to use the file that it wrote hasn't worked. Should I be letting it fix the errors it finds on the source when trying to make the image? I didn't want to screw up my mostly working card and not have a usable unit anymore. And of course it did it's usual temp and temp graph freeze just after putting the old card back in to use it.
