You might check into the tool  

PDSE and HFS Analysis Tool (PHATOOL)

The PHATOOL is a service aid that operates as a application program. Its
purpose is to check
and analyze the directory structures (such as AD and ND) and display the
allocation of data
set pages. Note that:
 The PHATOOL is not a PDSE verification tool.
 The PHATOOL does not perform a consistency check between the attribute and
name
directory structures.
 The PHATOOL does not check member data.

This is documented in the REDBOOK:  Partitioned Data Set Extended Usage
Guide   SG24-6106-01 (May 2005)


It might show you the fragmentation in the Directory of the PDSE which could
allow you to verify a need for a reorg.

Depending on your z/OS level there was a split in z/OS V1.12 (I think) where
a new program for PDS/E datasets was created by IBM so you did not need to
use IEBCOPY.
