Chosen Solution
I’m replacing my iMac 1Tb HD with a Critical 1 Tb SDD HD that I got from IFIXIT. Need to initialized the new SDD HD for cloning using Disk Utility in macOS Mojave. Followed directions on IFIXIT video on YouTube (https://youtu.be/saz0-c-218E) with no luck. (The YouTube video was released when the macOS was High Sierra. ) Disk Utility sees the new SDD HD, but Disk Utility/Ease fails. Yields: “Unmounting disk. POSIX Reports: The operation couldn’t be completed. Permission denied. Operation failed.” I ran Disk Utility/First Aid to verify that the new SDD was operational. Yields: “Running First Aid on “SuperDuper!” (disk2s1) Repairing file system. Volume is already unmounted. Performing fsck_hfs -fy -x /dev/rdisk2s1 Checking non-journaled HFS Plus Volume. Checking extents overflow file. Checking catalog file. Checking multi-linked files. Checking catalog hierarchy. Checking extended attributes file. Checking volume bitmap. Checking volume information. The volume SuperDuper! appears to be OK. File system check exit code is 0. Restoring the original state found as unmounted.” The new SDD HD looks good. I suspect this is a Mojave issue, but several hours of searching in the Internet has produced no solutions. Can you help?
SOLVED… The instructional video said to plug the new SDD HD into the USB port and run Disk Utility/Erase. This would not work for me. I restarted the computer with the new SDD HD plugged in to the USB port. At start up, I got a pop-up message about initializing the new hardware. I clicked OKAY and Disk Utility popped up. I was able to Erase and initialize the the new SDD HD. Then I used SuperDuper to clone the Mac HD.
Dan, mayer, Thanks for your input. Your solution seems to provide capabilities that mine does not have. I haven’t done this before. Can you direct me to a website or to a YouTube video that will walk me through your process? Thanks
