Fusion Drive Replacement Problems

Texte:

Here’s my situation!  In Oct 2019 I replaced the original Fusion drive with 1TB SSD drive but I can’t remember if I split up the Fusion drive before I installed the new SSD.  I’ve installed MacOS on that drive and it’s been running except for the drive access speeds being very slow!

So I thought I’d replace the existing 128GB PCIe SSD (that came with the Fusion Drive) with a faster 1TB version.  I just got that done, but now Disk Utility doesn’t see the new PCIe SSD - it does see the old SSD that I replaced the Fusion drive with.

That got me thinking and I can’t for the life of me remember if I ever split the Fusion drive up before I did the original SSD replacement in 2019.  Also, I don’t think I ever saw the 128GB PCIe drive ever show up in Disk Utility before the replacement a couple of days ago.

Do you think I forgot to split it up which is why I can’t see that drive (the original 128GB SSD or my new 1TB SSD)?  I’ve reset the PRAM and SMC and rebooted into recovery etc.

I don’t want to have to open up the iMac again, so if there’s anything you guys can think of to try please let me know!  (diskutil list only shows the SATA SSD drive)

Thanks!
