The errors described in this section include damage to the header, the records, or the keys.

IF THE BLOCK IS LEVEL ZERO (0), use DSE DUMP to examine the contents of the block. Note any information that might allow you to correct the problem or might help to identify and recreate the endangered data. If you are familiar with GDS and hexadecimal representations, you may be able to recognize data that DSE cannot recognize because of misalignment.

IF THE BEGINNING OF THE BLOCK IS VALID, DUMP GLO may be able to capture its contents up to the point where it is damaged. In the worst case, REMOVE the record that points to the block, MAP it FREE, and lose its entire contents. The extent and importance of the damage depends on the size of the block and what it should be holding. In a similar but not quite as drastic case, REMOVE the record with the problem and lose the contents of that record.
