Thank you. I thought I was losing my mind ( what there is to lose ) in that I was getting weird behavior from my disks or ssds in these old boats. Could just be bizarre Apple hardware. I think what I shall do is boot ye old original Apple label Hitach disk and then do a backup to an external USB attached brick. That way I have all my Debian sid ppc64 work saved away. Maybe I will fire up another G5 brick but those damn things really put a drain on the UPS for what they do. Perhaps QEMU will be okay for my Debian sid ppc64 work. Regardless I have greater interest in FreeBSD UNIX and I realyl would like to have at least two or three risc machines running. Namely RISC-V and PPC64 and a SPARC unit for local flavour. I have a ton of SPARC laying about. Also a metric ton of PA-Risc HP Superdome gear in my life. However that is a whole other story and only Helge Deller could make those work. So anyways ... I will try with the original Apple part disk in the correct slot and then there are no excuses. Dennis
