Comments about GSmartControl as an Alternative to CrystalDiskInfo
It doesnt support NVME SSD's which was the WHOLE reason I wanted to chcek the smart stats. This useless pile of junk just says it is an unknown device! The disk in question is a fully SMART compatible NVME SSD from a major disk manaufacturer - if this program cant identifu it it isnt much good!

Works pretty alright, enough for my needs, though there's some values where it will say "pre-failure" for even the values you get out-of-the-box with a new drive, something to be aware of.
To respond to the one negative comment, all drives will show as "unknown device" IF you don't run the program with admin privileges -- even my SATA HDDs and SSDs will display as "unknown device" if I do not have superuser privs.
