So that means that the > disk was NOT the problem in our case? Hmm, I am not certain. The block was filled with zeros from your error message, and I think such blocks don't trigger a checksum warning. So if your disk replaces a valid block with zeros (filesystem check after crash?), that could explain what you see. Yours, Laurenz Albe
