hgsgs Posted February 27, 2019 Share Posted February 27, 2019 (edited) Hello!I have MacMini Late 2014 with HDD drive with El Capitan.I bought SSD Samsung Evo 970 M2 and NGFF Adapter.I have added patch-nvme by RehabMan using Kext Utility (https://nickwoodhams.com/getting-your-nvme-ssd-working-on-macos-sierra-10-12-2/). After that Mac showed my SSD.I tried to erase it with DiskUtility, but had an error: diskutil eraseDisk JHFS+ UntitledUFS /dev/disk0 Started erase on disk0 Unmounting disk Error: -69825: Wiping volume data to prevent future accidental probing failed I tried to format it using fdisk and had success: sudo fdisk -f boothfs /dev/disk0 sudo fdisk -i -a boothfs /dev/disk0 diskutil list /dev/disk0 (internal): #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme 250.1 GB disk0 1: Apple_Boot 8.4 MB disk0s1 2: Apple_HFS 250.1 GB disk0s2 After that DiskUtility had the same error. How can I format it to HFS with GUID partition scheme? What should I do next to install El Capitan on SSD? I think it will be some problems with installation because new instance of El Capitan on ssd won't have patched kext. How can I solve this problem? I know that everything will be ease if I install High Sierra, but I need El Capitan. Edited February 27, 2019 by hgsgs Link to comment Share on other sites More sharing options...
