My KiKi system has lived through many a power outage (our winters are hard on power lines), but from the most recent one it has not recovered.
I feared for the mobo at first, because both Win10 and Mojave were no longer bootable. Win10 reported its boot disk damaged, tried to repair, then failed to repair. Boot attempts just get me back to the American Megatrends BIOS splash screen. So that's annoying... looks like Yet Another Reinstall. Mojave OTOH gets as far as Intelmausi internet kext, then hangs.
So... I got out my handy Mojave rescue SSD and tried that. No problemo. Boots fine. The good news is, the mobo seems OK and my user files seem to be intact. So I used Disk Utility to repair the Mojave boot disk. Tried again to boot Mojave, but no luck. It gets past Intelmausi kext now, but then fails and ends up back at BIOS. So now I'm in a rather awkward position... I guess my EFI partition might have suffered damage, so I'll try replacing it with the (older) one off the rescue SSD. That will put me about a month into the past wrt patches and bugfixes, but it might at least make KiKi bootable again...
The question I have about this sad story is this: are these internal SSD drives notable for their fragility? It seems odd that both boot disks (Win10 and Mojave) are internal SSD and both seem to have become corrupted after a quite ordinary power hit while all the other connected disks seem OK. It seems even odder because Win10 was not running at the time and its boot disk is not mounted by Mojave. It should have been completely idle.
The obvious strategy is to keep bitwise copies of both disks around, so I can restore them more easily when this happens. But it would be nice to know whether this is going to keep happening
My old Hack, GiGi, has always used an nVME internal SSD for boot disk, been through many power hits, and never had any issues. Is it my mobo? (ASUS MAXIMUS HERO XI)
Win10 has corrupted itself and forced a reinstall from scratch once before, and that's more or less what I expect from that OS. But I'm rather annoyed by Mojave shooting itself in the foot. Never had that happen before. Any comments, ideas, etc?
A bit of googling suggests that SSDs are, in fact, notorious for their fragility wrt unexpected power loss. However, I find it hard to explain the spectacular robustness of the nVME SSD in my first Hack, vs the apparent fragility of the two in my 2nd Hack. They're all reputable brands.
