I have a 1TB external WD My Book 1110, last night while I was browsing for some old files in there I started getting data access errors while trying to open a certain folder, everything else seemed OK, although a bit slower than usual, which at the time I had thought it was the computer itself being slow.
I researched online, and ran the cmd to try and find out if there were any errors in the HD using:
chkdsk G: /f /r
It found many file segments unreadeable, and ultimately the process failed due to a so called unexpected error, I ran it again with the same outcome.
Since that didn't seem to work, I got HD Tune 2.55 and ran the complete error scan text, after many hours it came out basically fine, or at least that's what I thought:
With the exception of that one little red block there, the rest appeared to be ok. I've had this HD for a few years now but I only use to store stuff I'm not currently using, so it hasn't really had that much use over time, and it never seemed to have a factory defect either, so my question is should I be concerned? I've gone through other files in the HD and haven't had the error again, so I'm not really sure if I should start emergency measures already or if it could've been sort of a false positive.
I got Western Digital Data LifeGuard Diagnostics from the website and ran a quick scan:
Which failed with this error:
