    Description

      The data_size column is calculated using (HWM+1-BLOCK_OFFSET)*BLOCK_SIZE. But for multi-segment files the HWM for the lower segments is 0. This means that the lower segment shows a size of 1 block and the last segment shows a size of one extent segment.

      This should probably show 0 for the lower segments and the entire usage for the upper segment if possible.
