Disk error- Interpreting SMART test

bluetwo12 · October 27, 2023

Here is my short test. I am pending the long test but wanted to get a jump start on some deciphering. I have also deleted stuff on unraid (movies) through windows. I assume this wouldnt cause these errors..right? It showed 400 errors on the unraid array page

Edit: Added full extended test at end
