Hi, The problem with this is that the blocks couldn't be recovered because you used the NOLOGGING option. They are therefore flagged as corrupt. You may have found that blocks flagged as corrupt will have been logged in you alert log during the recovery operation. All of the objects that were created using NOLOGGING will be in the same state and it may be easier to tackle the problem from this angle rather than examining each block. If you're not sure which objects were created in this fashion then dbv will be able to identify corrupted blocks which you can then analyse in the manner you've described.
The indexes will still show as VALID because in a logical sense nothing has happened to invalidate them. The fact that the blocks comprising the indexes are corrupt is (in a data dictionary sense) immaterial.
