machaon83 Posted April 18, 2020 Share Posted April 18, 2020 Hi guys.My HighSierra installation works like a charm since two years on a Gigabyte H370 HD3.Yesterday evening, I launched a "clean my mac" clean up, two actions were done : Free 20Go of disk space on SSD system disk (a lot of system and browsers cache) Launch maintenance script One hour later a power cut crashes the system.And after... clover (v4630) don't see my SSD System disk anymore, the list of partitions to boot one is empty (or just the USB install key) In the UEFI (bios) the motherboard perfectly recognize the disk.I also booted on a fresh installed USB HighSierra USB key, launched disk util and launched SOS on it, result :invalid_bsdflags (see capture 1) but disk util conclude : "everything is ok" after each launch.In terminal I can navigate on directories, evrything seems to be fine except the /EFI/ folder is missing at the root of main partition.I've no more idea to fix my problem... any help or suggestion ?Thanks a lot guys Link to comment https://www.insanelymac.com/forum/topic/343474-power-cut-and-no-reboot/ Share on other sites More sharing options...
machaon83 Posted April 20, 2020 Author Share Posted April 20, 2020 I reinstalled HighSierra on the existing SSD partition and everything was fixed with no data loss.
