Try to remove reallocation and background processes - also check MCMT

Baseically LED:BD means damaged SMART system file(s).
Bad based on your provided story - could be damaged one or few (any) system files, necessary to check thaem by Ctrl-x report.
Also could be haeds issue (they can't write), you didn't check them and after modified 93 writing attempt it became damaged.
With best regards
