MP 1,1-5,1 Two NVME SMART failures in a few weeks.

[Jigga Beef]

So I had a Samsung NVME 960 EVO as my boot drive in my Mac Pro 5,1 connected via PCI-E working great for about 16 months. A few weeks ago I couldn’t boot and when I tried to reinstall the OS it said the drive had S.M.A.R.T. status issues and could not install the OS. All of the data was still accessible so I just bought a new NVME 970 EVO drive about 3 months ago, installed the OS, and moved over my data EZ PZ.



Last night I had the same issue with the new NVME drive crap out connected the same way. This time the data seems to be accessible still as well. But I cannot reinstall the OS to the NVME drive



Seems odd to have the SMART failure on such a new drive so I am assuming I must be doing something wrong. Should I replace the PCI-E card?



The inside Temp of the machine is the same as it has been for years. Any other steps or things I can check.



The PCIE card I have is

OWC Accelsior 1M2 M.2 SSD to PCle 4.0 Adapter Card with the heatsink installed.

Do you have a utility program that tells you exactly which SMART attributes are reporting errors? If not, try installing DriveDX (it has a free trial period) and see what it says. Then post back here.

At the moment I'm more inclined to suspect your adapter than the NVMe.

S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) is a process run internally on an HD which is then reported to the external OS. As such, a connector/adapter issue seems less likely to trigger a S.M.A.R.T. than something within the confines of the HD. But yes, one needs to know the specific warning before moving forward. https://en.wikipedia.org/wiki/S.M.A.R.T.
