![]() Since my 970 Evo Plus 2B2QEXM7 firmware was already MacOS compatible (I updated it when I installed it in 2020), I figured I'm done messing with firmware.Ĥ) I put the iMac back together and installed Ventura 13.1 from a bootable USB drive I'd prepared.ĥ) When MacOS was done installing and at the setup portion, I selected to restore using Time Machine. After many attempts, I searched online and found out that the 4B2QEXM7 firmware is targeting only certain specific drive serial numbers. I was able to update the 870 but the 970 EVO Plus kept saying there was no drive matching to update. So I disassembled the iMac, removed the drives, installed them in my PC. I tried various methods (Etcher, dd, unetbootin) and different USB flash drives but the updater would just hang and not boot into the update OS (stuck at a black screen with a square white cursor). I created bootable USB drives and attempted to update them while installed in the iMac. I also noticed updated firmware for my 870 EVO "SVT02B6Q for Mac". I noticed there is a 4B2QEXM7 firmware on Samsung's site. For Samsung Driver, use Samsung Iso installed via terminal see:ġ) I backed everything up with Time Machine to an external HD.ģ) My 970 EVO Plus has firmware 2B2QEXM7. Import your account files from TM backup in preference to Migration Assistant. To quote Mike Bombich: ‘Copying Apple's system is now an Apple-proprietary endeavor we can only offer "best effort" support for making an external bootable device on macOS Big Sur (and later OSes).ĥ. Absolutely do not clone system Big Sur and above as Apples system is now proprietory. Install NVME clean and format when installed as part of Recovery o/s installationģ. HDD failure is usually preceded by noises or odd behaviour so there is better warning.Ģ. SSD failure happens suddenly without warning. However, SSDs reported more errors than the HDDs, with more bad blocks and uncorrectable errors’. They also reported that Google replaced SSD drives about a quarter less often than HDDs. In 2016, Google and University of Toronto reported the results of a joint 4-year study that tracked SSD and HDD reliability in Google’s data-intensive data centers.The study demonstrated that the age of the SSD was the main factor in drive failures. ‘However, some real-life tests allow us to draw reasonable conclusions. In fact there is a persuasive argument for critical backup to be preserved on HDD according to Enterprise Storage Forum: Aim to keep them separate as Fusion created with 2 SSD’s is high risk error. Split Fusion Drive into individual drives before upgrading. Ref discussions MikeHalloran, Dobrink, Mboss, MBerhr2 and rxs0ġ. I had to use Paragon Disk Manager to reformat the 500gb space for the Mac, for some reason Disk Utility wasn't able to.Ī very good idea.I cannot pretend to be an expert, however there are a few points which I this forum demonstrates are essential. Maybe I'll find a way to get those going, but for now, this works fine. Brightness control and volume on keyboard does not work. But using my USB speakers, sound is working fine. No sound through the headphone jack or internal iMac speakers. Windows didn't like any of the partitions I made, so I removed them all in the windows installer and let it create 500gb of partitions it liked. Reboot, boot to the USB stick, install windows 10. Copy the Bootcamp drivers using Bootcamp Assistant to the USB stick. Using VMware with Win 10 on Mac, create a bootable USB drive with windows 10 iso using Rufus. When I get to the step to plug in the external and pass it through to the VM, Windows 10 makes a bunch of connecting/disconnecting sounds, but the drive is never visible in Disk Manager to manipulate the partitions and install Win 10 on there.Īttempt #4: Re-install 1TB SATA SSD inside the iMac. When I run it from the terminal, I get the message that there isn’t enough free space, yet there is more than a terabyte of free space.Īttempt #3: Remove the SATA SSD from the iMac, put it into an enclosure, create an external Windows 10 SSD drive. Bootcamp assistant is still cranky and gives me an error stating it can’t partition the drives. I’m able to get the 1.5TB fusion drive set up using terminal commands. ![]() However the fusion drive is split and I get an error when I try to run the bootcamp assistant to get my windows partition setup again.Īttempt #2: Re-build Fusion drive with the two SSDs. When I powered up, it booted to macOS successfully. I then opened the iMac and swapped the drives. Attempt #1: Post upgrade, I cloned my macOS using SuperDuper to the Evo Plus in a USB-C NVME enclosure.
