I would think Percentage Used would be the more accurate number, rather than Available Spare. So the anomaly again: Available Spare: 100% So all in all, no errors and no need to start using the spare blocks.įor comparison, my 2017 iMac Pro that I bought in January 2018 (I think): (base) Johns-iMac-Pro :: ~ » smartctl -a disk1 Unsafe Shutdowns: 20 Probably the number of kernel panics I’ve had.

The /dev/nvme0n1p2 is my primary data partition, but I also want to make sure the others aren't corrupt, so presumably I would want to check one of the "parent" partitions.Continuing the discussion from Microsoft committed to Right to Repair, will Apple follow suit?: The general usage for smartctl is to run something like: sudo smartctl -i /dev/sdX ![]() Fortunately, rebooting has temporarily resolved the issue, but I'm trying confirm that the issue is a degraded ssd and not something else, like a faulty motherboard. ![]() My laptop, which has a NVMe solid state drive, has been crashing somewhat frequently recently with strange disk read errors.
