iMac SSD upgrade from Fusion drive, SSD seen as Fusion drive still?
I have upgraded 27” 2014 i7 iMac running a 1 TB Fusion drive to 1 TB SSD drive.
I have done many upgrades normally from standard SATA drive to SSD drive and works fine. After initialize new drive and format it in disk utility the SSD drive comes up as 1 drive.
However, in this upgrade, upgrading from Fusion to SSD I found that initialize went smooth and format also on another iMac but when I try to run disk utility to format it and install Mojave I see the 1TB SSD drive actually still as fusion drive.
A 1TB SSD drive should be as 1 drive but its actually coming up as 1TB SATA and 121.33 GB SSD.
It’s coming up as:
- 121.33GB (disk0)
- 1TB (disk1)
Would anyone one know how to fix this?
I have done in the past merging the 2 partitions on a 1TB SSD drive but it turned it into 1.12TB Fusion drive and I confused how it adds from nowhere the 121.33GB SSD component when in fact the SSD is only 1TB in capacity. Below is the instruction to fix a split fusion drive into one but is there a way to somehow remove the memory of the fusion drive on this particular iMac so it realises it now has a SSD drive as I am thinking that it’s got the memory of the old fusion drive details and not sure how to change?
I’ve also tested 2 other SSD drives (different brands/capacity) and the same thing is happening - they are appearing as 2 drives (split as fusion drive).
The weird thing is I have tested a standard 1TB SATA (non-fusion) drive from another iMac and its also coming up as Fusion drive in the disk utility so it as if it doesn't matter what drive is tested it defaults to fusion drive based on the initial factory fitted drive it came with (very strange)?
I have reset NVRAM/PRAM and SMC and no success at all (thinking it would reset the chipset and register the new hard drive but it hasn't).
