Dell diagnostics produced Error 2000-0142 during self test for HDD.

Hi

For last couple of weeks I'm having trouble with my laptop, e.g. inaccessibility to folders and sudden hangup. So today I ran DELL Diagnostics and it produced error code 2000-0142  (I attached a screenshot of it). I searched the community and learned that this message means that my laptop HDD is failing!! What should I do now?

Thanks in advance.
