Support Assist Warning message lacking detail?

Hi All

My PC hasn't been running well recently (sometimes slow to respond) so I opened up SupportAssist, Toubleshooting and selected the "I want to scan my entire PC".  The report showing a "warning" message next to my hard drive.

Having two hard drives I then selected the "I want to check a specific piece of hardware" scanning my D drive then the C drive.  After the scan on the C drive it showed it had been scanned but had the "warning" message again followed by a green tick.  I when into History and again, it shows the warning message.  I thought i needed to run a "long test" to get a more detailed report so i did but once again all i get is a "warning" message.

Only problem is, i have no idea what the warning is about.  Is there a software/driver error?  Is the physical hard drive itself failing or showing signs of failing?  Is there a lack of power?  Or is it something else?

Basically i'm after a more detailed report rather than just a vague "warning" message so i can either fix it or go about replacing it before it's too late (i.e. I lose data).

I've ran Scannow in cmd, which reported no problems.  Performing a Scan-disk returns no errors and i've done a Chkdsk via cmd as well.  I still get this "warning" message via Support Assist.

Any help/advice would be appreciated.

Thank you
