In VMCE 1.1.1, I added the VM50U0 and VM50U1 as user pack volume serial numbers. Those packs are empty in the distribution, and those names (or anything of that name pattern - VM50Ux) will never be used to distribute VMCE content.?Ren¨¦, I suggest you use those names for your private?data minidisks. When a new VM release comes out, just copy those disk volumes to the new release, over top of the empty ones we supply and update the USER DIRECT file appropriately. Also copy any shadow files for those?User volumes.
