What it means
An Index Allocation Map (IAM) page or metadata entry was not located, even though a reference to the page exists as the previous page link on another IAM page in an IAM chain. If the P_ID1 page is (0:0), the IAM page, P_ID2, is the start of an IAM chain, and the metadata entry for the IAM chain is missing.
