This is VM, anything can be done ;-) With DDR (or "trackread" in CMS Pipelines) you can see the virtual cylinder number. If you would scan the entire pack cylinder by cylinder, it would nicely show you where the mini disks were. If it's a CMS mini disk, the VOL1 record has the number of cylinders that CMS had, and you can normally skip the rest of that mini disk in your scan. Alternatively, you can DDR real cylinder 1 to a small T-disk and try ACCESS to have CMS tell you what was there. That information gives you the amount to increment your cursor and try the next disk. I've also seen people use DEF MDISK but I like it less because it goes R/W... | Rob
