siachori Posted May 17, 2020 Author Share Posted May 17, 2020 SOLVED with this solution on High Sierra: <<UltraBay HDD When using HDD in Ultrabay (instead of optical drive): install AHCIPortInjector.kext and AppleAHCIPort.kext in /Library/Extensions. AHCIPortInjector.kext fixes the Disk not initialized issue (disk cannot be read). AppleAHCIPort.kext fixes the disk being detected as an external drive (instead of internal).>> Thanks for all friends Link to comment https://www.insanelymac.com/forum/topic/343871-ultrabay-hdd-always-disk-was-not-readable-by-this-computer/#findComment-2722757 Share on other sites More sharing options...
