So, now you know about -F switch :) There is possible two cases: 1. When you have not PMBR and primary GPT is damaged, you will see the message about corrupted primary GPT. 2. When you have not PMBR, but have correct primary GPT. In this case seems all will looks good. I think we should report about such corruption. Thanks. --=20 WBR, Andrey V.
