We recently got a corrupted PO data set after using the PDS command to add directory blocks. During the FIXPDS operation we were prompted to move members to make room for additional directory blocks. SOP. We have done this so often for such a long time that we didn't hesitate. Afterwards, however, the PDS was unusable. The only unusual thing about this PDS was that it was created (per ISV JCL) with only 1 directory block.
I have a dim memory of learning ages ago that a PDS with 1 directory block is somehow 'different', that certain updates to it require fiddling with the VTOC in addition to changing data on a track. Sound familiar? . .
