| Console more or less keeps a running log in real time of all the processes on your Mac. Each event is time-stamped. In my case I noted several "disk 6s3 i/o error" entries, along with reams of other code I do not understand at all. I checked Disk Utility for clues but it does not show the device ID of the drives, just what you named them so I made the (incorrect) assumption "disk 6s3" was my boot drive. Eventually I discovered that you can open Terminal, type "diskutil list" and it will return a detailed list of device ID's as well as their "names." Aha. "Device disk 6" was that faulty Firewire drive. By the way, along the way I bought (again) Disk Warrior which was no help at all, booted into Safe Mode and ran the RAM hardware test overnight, bought MORE RAM in case the whole lot was failing, and backed up then wiped clean an SSD for the clean installation of the OS. It was an expensive and time-consuming experience but I learned a lot. I have always shied away from Terminal; and never used Console in my life before a couple of weeks ago. But it turns out that with some digging around online you can find a load of useful troubleshooting techniques that do not put your machine in further harm's way. Robert W.
