THANK YOU. SO IF I AM NOT HAVING ANY PROBLEMS, IS IT OK? OR JUST SOMETHING SIMPLE AND SAFE?
"DST" short test stands for "Drive Short Test", which means your hard drive has failed or is failing as reported by the SMART chip info.
What this means is that your hard drive is close to dieing means you won't be able to get any data off of it or use it to load Windows, etc.
It means, it is time to replace the hard drive. Useing it is risky at this point if you store anything on it.
