Q: Hard drive and Apple Diagnostics issue

Hello!

 

I have two questions.

 

1) I wanted to check my Mac with Apple Diagnostics, but holding down D did nothing. Mac just sat there, screen black, then after 30 - 60 seconds, Mac did this sighing noise like it went to rest or breathed out air and then nothing. I had to force is shut to get screen working. Apple Diagnostics not working? I tried with Alt D as well, but nothing. Or am I supposed to keep holding it back for ten minutes or something? I held it for several minutes but nothing.

I really do not have any visible issues, just wanted to be sure.

 

2) Does Apple Diagnostics measure Hard Drive errors as well or is for that Disk Utility First Aid?
