Hello @SkuchiesTV 

Short DST (Drive self-test) failed means your (hard/SSD) drive has to be replaced !

You have to remove the current (hard/SDD) drive and install a new one. It depends on which drive was used

(1) mechanical 2.5" hard drive   <--- I guess that it is this one

(2) SSD drive

...

Assumption:

Nothing will happen to your data. Later you can use adapter (USB-to-IDE/SATA) to access your data.

Keep in mind: If there is a serious drive error, you may not be able to read all data. But it is always worth a try.

Do you need more help ?

To help you I need to know the product number (p/n) of your notebook !

You will find this information on the back/rear of your notebook in small alphanumeric letters.

The product number (p/n) is legally allowed information about notebooks. This is not sensitive data.

It is allowed to publish it in public.
