Solved CrystalDiskInfo columns missing?

wiganken · Aug 14, 2023

I installed CrystalDiskInfo v9.1.1 and when I run it I do not see columns 'Current ¦ Worst¦Threshold'. First photo (a screenshot from this forum) is what I expected to see and second photo is what I actually see. Any ideas as to why I am not seeing the missing columns? Is it a configuration thing?

Just thinking out loud here, but it may have provide different information dependent on the type of disk. The first screenshot is for a spinner. The second is for nvme.

Could be. I have tried uninstalling it and reinstalling but get the same screen.

I also installed the same app on my DELL which has a SSD and there I see the missing columns. I'll check it later to see if that is also nvme and get back.

Yes, it is due to NVM Express. I have 6 drives and only get the raw values column with the NVM, but the other 5 SSD shows all the columns as in your first image.

Okay. Thanks. I see my DELL SSD has a Serial ATA Interface (see photo) and shows the columns so confirms what you guys say about Nvme.

Observation - CrystalDiskInfo is no use for problem solving Nvme connected SSDs. All one sees that is relevant is "Health status" "Good 99%". I don't see the RAW values as being much use. Seems that the app is of little use on Nvme connected SSDs.

Question - Is this correct or am I missing something?

This is how I set up mine,

In case I am missing something can anybody confirm this please?

You are correct, only ATA drives have manufacturer defined thresholds. NVMe drives have a completely different set of SMART information. There are no thresholds defined for NVMe, so none to display.

ATA S.M.A.R.T. attributes
Each drive manufacturer defines a set of attributes,[21][22] and sets threshold values beyond which attributes should not pass under normal operation.[17]

Self-Monitoring, Analysis and Reporting Technology - Wikipedia - In ATA

In NVMe
NVMe specification has defined unified S.M.A.R.T. attributes for different drive manufacturers. The data is present in a log page of 512 bytes long.

It is a bit easier to understand:

Function>Advanced Features>Raw Values >10[DEC]

Thanks for confirming.

I don't understand what this means but it doesn't matter. Thanks anyway.

I'll uninstall the app from my HP machine, which has NVME SSD. That's all I need to know. I'll call this thread 'Solved'.

@SIW2 - Thanks but is that the default setting or will selecting that cause more information to display than currently appears? By 'more information' I mean information that will be of use in troubleshooting an NVME connected SSD.

I can't check it myself since I have uninstalled CrystalDiskInfo (CDI) as 'not useful' on this machine.
Note that I am not experiencing problems on the NVME SSD machine. I am simply trying to understand the limitations of CDI.

That's how you change the setting to show as my post #6. Info easier to understand.
Another setting is to show the temp of the drive in the notification area. When I create an image with Macrium it shows the temp rising, especially during the verification phase. You can also set hight temp alarm. Just a way to keep an eye on the temp.

This showing in sys tray,

Okay. Understand now. This just shows the 'Raw Values' as readable numbers but, without context they do not mean much.
This further confirms that CDI is of limited use on NVME SSDs but at least I know now.
