Stupid Mac question!

[Freakuk]

I'm going to take a stab at the HDD starting to fail within the Fusion drive, I'm saying this as I had a 27" iMac with a 3TB Fusion drive and about 3-4 years old it really started to slow down, I could hear a faint knocking every now and again which led me to believe the HDD had errors and this was constant retries.

I contacted Apple who provided a tool to verify the disk, but it never completed a run. Eventually I took the iMac to a specialist Apple store who confirmed my suspicions and the Fusion drive was replaced FOC.

Quick update. 1tb SSD turned up this afternoon as did the enclosure.

Downloaded latest MacOS onto it and installed. When it rebooted, it asked me if I wanted to use Migration Assistant to transfer everything over, I said yes and it's done everything for me! Then went into Disk Utility and unpartitioned my Fusion Drive and erased it.

Now I have everything on the external SSD and not even going to bother with the Fusion Drive (although I might see if I can backup (is it Time Capsule) to it.

iMac now running super snappy and how I expected. For under £60 it was certainly worth it! If I'd have spent £2,500 on this in 2015 when it was new, I'd have been mightily disappointed. I've been used to the MBP with the SSD from new so this was like going back to the 2000's.

Thanks for all your help guys!

I have done the same thing with my 2019 27" imac. I use the fusion drive as an additional drive to store data on as well as an external HDD as a time machine.
