Any chance one of you is measuring thingamajigs and the other doohickeys? A card image dataset with 10 records contains 800 bytes of data but occupies one track. One thousand of these contain 800KB but consume 5.6MB of 3390 DASD. It can get even worse if there are unused tracks in the last extent or if the dataset needs to be reorganized (e.g., compress the PDS). If the 70TB is based on tracks and the 40TB on content, there might not be a discrepancy. (And yes, I was surprised that both words passed the spell checker.) ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
