hi! I have a late 2012 iMac with Fusion Drive. A year agothe HDD became defective and I was forced to split the Fusion drive between the HDD and SSD. Doing this allowed me to do a fresh install of macOS onto the SSD. The problem now is every other boot up macOS detects the defective HDD and tries to mount it. This results in a slower boot time and login. macOS would eventually give up and report that I should manually "eject" the defective drive before "unplugging it". Now, is there a command where in macOS will not mount the defective HDD at boot? I was toying around with installing a 10TB or 12TB HDD to replace the defective 1TB and make a new Fusion Drive but I fear breaking anything more. I have the install kit from OWC to replace a drive but I am a bit hesitant.
