Failed logic board. How can I access Fusion Drive contents?
The machine has failed in a way that makes it unusable (shuts off when in use, soon after powering on). I believe the logic board has failed as I have replaced the display and the power supply and the machine is still unusable. Now I just want to recover the data and transfer it to a new machine. Unfortunately the original machine has a Fusion Drive, so I don’t think I can migrate the data by removing the HDD and SSD and connecting them to another system externally using enclosures. But I also can’t use Target Disk Mode to transfer the data because the original machine won’t stay powered on. Can anyone offer some advice? I just need to recover the data. Thank you!
Is dit een goede vraag?
Sorry to necro this. Was this ever figured out?
I have the exact same problem. Failed iMac 2017 logic board, took out the 3tb HDD portion of the fusion drive. Tried to mount on a new iMac and got the error ""Could not mount 'disk2s2'. (com.apple.DiskManagement.disenter error -119930868"
First aid runs fine on the parent disk "disk2" and says "The partition map appears to be OK" - But I cannot run first aid on "disk2s2" because it won't mount

@marcopolos - Sounds like the HDD is failing. Have you made a backup and maintained it? If not you could try using Target Disk Mode using a second Mac to access what you can and then look at replacing the drive.
