make backups of your files
Folks, I just had to tell a customer that they likely lost everything on their computer. They brought it to me saying one day it was working fine and the next it went black. I couldn't get their HDD to recognize at all in any of 3 testing environments.
Make backup copies of your files, and save them on removable disks. If you haven't done it in a while, do it today.
computers have come with smart-capable hard drives for most of 15 years now, & windows still doesn't have a smart monitor or notifier of its own.
