Hi @uco73 ,
Although it's not a question directly related to Dell even if it happens on a Dell machine, let me try to see if anything helps.
According to this thread from HDSentinel forum, Windows Defender may somehow blocks access to disk status and information completely. See if those suggested method mentioned in the thread helps on your case.
Welcome to the Dell Community @uco73
It is drive specific what information it will display.
An SSD does not have all of the same "SMART" attributes as an HDD.
I notice that some SSD's do have temperature readings and some do not.
I test and "DOD Wipe" hundreds of HDD's and SSD's every week. "Using Sentinel"
Some model SSD's will show the drive at 50% but is perfectly fine.
Not sure what the difference is???
Maybe the version of the drives are different???
Take a look.
Let me know what you think???
