One of them had that same extra Tries = 2 at the same place. I'll do a couple more just to see what happens. I'm happy to watch it as long as it takes and will certainly save any results if and when a drive isn't found. This problem has run hot and cold for a few months. Sometimes I go a week with every boot is good. This last two weeks was finally bad enough to get me to report it. I also want to investigate actually getting the BIOS AHCI setting working, but I think I'll leave that alone for afew days so as to not upset this experiment. Performance on the machine isn't critical right now, assuming AHCI helps. I'll get back to you when I've got something new to report.
