Is an HDD required?
I discovered the HDD in my Fusion Drive 27" 2017 iMac was dying/more-or-less dead, and decided to try my hand at using an OWC Aura kit to upgrade the iMac.
I split the Fusion drive and then disassembled the iMac. I've inserted the new OWC Aura drive (2TB to replace the 128GB that came with the iMac), and done most of the re-assembly.
However, before I close it back up with the adhesive, I'm unclear on one thing: if I leave the HDD bay empty and the SATA cable unattached, will the iMac work correctly with just the SSD inside?
It would be annoying to close the iMac up and then find that it won't run properly, so if I need to buy a replacement HDD to install, it would be good to know that first.
Thanks in advance,
As a follow up, I notice from this OWC video (https://youtu.be/ROVQLonvs8Q) that when they add in a replacement HDD they use a new SATA connector with a temperature sensor, which isn't present with the drive that came with the iMac. If I do have to install a replacement HDD, do I need to get a new SATA connector with a temperature sensor?
Is dit een goede vraag?
