I have an older WD2500KS drive. I have only had it for a few years (actual Powered on Time is 1.4 years.) It recently had an issue with slow access to the disk and when running windows utilities it found bad sectors. I ran WD Lifeguard Tools and it does find errors, but when I go to repair them it gives me an error. I assumed this meant it was failing. However, the SMART status in Windows shows that everything is fine (all checks are green.) In Linux though, there is 1 warning under “Current Pending Sector Count” and everything else is green. The warning shows that there is only 1 bad sector.
So what I want to know is, is this drive failing or does 1 bad sector mean a simple error?
