How to repair a Fusion Drive (or split it up)…

If you own an iMac 2011 – 2020 or a Mac mini 2012 – 2014 you most probably have a Fusion Drive – a combination of SSD and HDD. In this video I show you how to set it up (if it was messed up) or how to split it (if you maybe want to install macOS and Windows on separate drives)!

Jessie: Thanks for interesting video. I have questions: 1. I have upgraded small NVME SSD to 2TB NVME after updating Larger HDD to 4TB SSD. I have no Fusion structure any more. If I want to restore fusion drive, you stated that I have to back up both drives. I understand that I need to delete both drives before recreating fusion drive. But only the regular SSD I am using as main drive has Mac Os 14.3 and new NVME SSD has no Mac Os. Do you know what is in the 32GB NVME drive ? any Mac Os inside and if so how do I clone or move the files into the new NVME drive ? My concern is if I delete regular SSD drive, there would be no Mac Os, I think, so I cannot boot into iMac any more. What is the benefit of restoring to fusion drive ? Both of my SSD drives have much faster speed than regular HDD, 3, 500 Mbps and 550 Mbps respectively. Even if I passed the stage of restoring fusion drive, how do I install my files to fusion drive ? I think carbon copy cloner cannot do that any more like in old days since Os Big Sur. Please advise if I should do separate drives as Mac and window and if you can do a video about that I am very willing to see and discuss. I have closed up my iMac after SSDs upgrade before your video released a day ago so I don't want to open it again if that is not worthwhile doing it again. I would appreciate your advice. Thank you very much.
Hi jessie i upgraded my mates iMac 2013, and put in a second drive 2TB samsung pro in the fusion slot where it was missing, both drives are SSD were showing as split, when i installed Sonoma with OPCL patcher on the main drive 4TB ssd, the second drive in the fusion slot does not appear anymore. and i dont know hot to get back, hopefully there is away without deleting the main HD drive with the operating system.
I am running my 2014 Mac on an external SSD now but still have the old 3TB HD installed, to use this as storage or Time Machine backup, should I remove the Fusion link as described? But of a newly to macs but managed to install Sonoma following your guides so far. 👍
Excellent guide to a less-than-intuitive process. Many thanks, Jesse.
Wisely😉I ordered my SSD only setup from the very beginning. Even the Fusion Drive Option in end 2015 was technically far too old. However it was a quite expensive choice. Did not believe in marketing👍
Off Topic: I think this is the longest period of no update from OCLP ive ever seen. Are things just that stable that there is nothing to change ? Just curious. My system is working great !
I think, it‘s not very reasonable to keep the fusion drive, once you replaced the hdd with an ssd, because no point in switching data in beteween two drives, once both are ssd, it would only take capacity of the cpu
thx a lot Finally I can split my hard disk 👍
Hi. Why APFS is much slower than standart MacOS extended file system. I've got Macbook Air 2014. OS Monterey. Thx
…and then there were also disks which combined an ssd (cache) and hdd directly (I have such a disk in my OCL-patched MacBook Pro 17" as a second drive); first drive is an SSD, of course 😉
I replaced the Fusion Drive on my 2017 iMac with a new internal SSD using an ifixit kit. It works well. Can I merge the 1TB SSD with the 28GB as you showed. It’s annoying as I have to eject the 28GB if the computer goes off (eg power failure). For some reason the smaller SSD shows as disk 0?
Thank you for such a nice, clear, concise workshop on this problematic topic. After installing my fusion-drive iMac in another room, I got the no-entry logo on every subsequent attempt to boot the machine. Re-installing the OS from the internet won't work, as the drive is simply not detected by the installer. The only solution, at this point, is the one you so aptly demonstrate here (Disk Utility DOES detect the hard drive… but in two separate units, as you show here). Alas, there is a number of files I didn't get to backup before this predicament. Would you be so kind as to suggest some data-recovery strategies in a situation like this? Many thanks!
You are truly wonderful, I thank you and salute you for your great efforts
Nice and clear, thanks!
Thanks for the video! Today, I replaced the fusion disk drive in my 2012 macmini with a 1TB Samsung EVO 870 SSD – obviously much faster than the old fusion drive Best $89 I've spend in a while!
How is this applicable to Open core legacy patcher? How do i use OCLP to install OSX and keep it in fusion?
Can I use a larger external USB SSD as the fast part of a Fusion Drive ?
