Herewith the tale of my "AAARGHHHH" yesterday: Setup: Mac Mini running Lightroom 6 and Firefox as the only non-Apple software, OS 10.11. Lightroom catalogs are on the internal HD, the photos are on an external HD, and there is a Time Machine backup of the whole thing on a second external HD (all spinny).
History: Sunday night I was working on some photos that I hope to submit for The Book, when the system bogged down tremendously—as in running at slide-rule-and-Morse-code speed. Quitting LR and re-launching didn’t help; rebooting was s-l-o-w and didn’t help either. I ran Disk Utility on the photo drive, and got a message saying there was a problem it couldn’t fix. The backup drive icon showed up but wouldn’t open. Many experiments and sleep deprivation ensued. Yesterday morning the drives didn’t even show appear on the desktop. Last evening, I ran Disk Utility from the CDs that came with my Mac Mini (it’s not new!), and it now boots at normal speed. However, it does not react at all to having external drives plugged in—they don’t show up on the desktop, even though About This Mac System Information/Hardware/Firewire shows that they're connected. Two external drives are now connected to my MBP, and are working normally. The photo drive shows up on my MBP, but won't open, and Disk Utility tells me (in red) that it can't be un-mounted in order to be repaired. What’s going on? What can I do about it?
