The pointer entry of an index entry in the block is not preceded by the value X'6x', or the RBA xxxxxxxxxxxx of the next level index block or profile is not valid for one of the following reasons:

• The first 2 bytes are not zero.
• The last 4 bytes are zero.
• The RBA is not a multiple of 4096.
• For level one blocks, the RBA is not a multiple of 256.

IRRUT200 does not dump the index block if only the RBA is not valid.
