attributes shown for NVMe SSDs are suspect in many hardware diagnostic utilities. attributes with a Yes/No status for my NVMe SSD (see attached image) so I wouldn’t be surprised to learn that some of the S.M.A.R.T. HWiNFO only shows a short list of S.M.A.R.T. Some tools create “fake” SMART values from NVMe status so that it looks as if NVMe would report the same sort of SMART attributes.“. The CrystalDiskInfo home page at states “ NVMe support requires Windows 10/Server 2016 or later“, but HWiNFO developer Martin Malik posted on 1 that “ NVMe drives don’t report attributes like ATA drives do via SMART, moreover many SMART attributes are not standardized. attributes aren’t displayed in CrystalDiskInfo occurs because I have an Intel Chipset PCIe/SATA RST Premium Controller (which is not on their list of supported controllers). As of now I still suspect the problem I described in post # 2401622 where the Current / Worst / Threshold columns for my S.M.A.R.T. I submitted a diagnostic log on 1 as instructed at but haven’t heard back from hiyohiyo. …I would suggest contacting the author – see websites Contact Us page… I didn’t realize those percentages should be displayed until I read your column.ĭell Inspi* 64-bit Win 10 Pro v21H1 build 19043.1348 *Intel i5-8265U CPU * 8 GB RAM * 256 GB Toshiba KBG40ZNS256G NVMe SSD * Intel UHD Graphics 620 I’ve used older versions of CrystalDiskInfo v8.x and a screenshot I captured last year shows the Current / Worst / Threshold columns were also missing in previous versions as well. Thanks for posting about this utility, Deanna. If not, could this be because I have an NVMe SSD? Device Manager shows I have an Intel Chipset PCIe/SATA RST Premium Controller, which I don’t see on the list of supported controllers at. Is there a setting in CrystalDiskInfo (e.g., somewhere under Function | Advanced) where I can enable the display of these percentages?

attributes in the main CrystalDiskInfo v8.12.12 interface, just Raw Values. I’m not seeing the Current / Worst / Threshold columns (i.e., showing percentages from 100 to 0 %) for the S.M.A.R.T.
