Is the hard drive failing

hard drivesmart

I'm beginning to worry about my ~3yr old WD Green drive. In the last few days i've noticed that my media player is acting weird, it won't move to the next track after a song has finished and also won't play new songs when I double click.

So, I downloaded the "smartmontools" package and used "sudo smartctl -a /dev/sdb2" to check out the drive. Here is a snapshot of the output:

I'm worried most about the "Pre-fail" rows.. does this mean that the drive could fail at any time or what?

Best Answer

If you read the column headers, you'd see that pre-fail is the type of statistic that's collected not the status. The When_Failed column being empty should also give you some hints about whether or not anything has failed (nothing has).

When in doubt, read the manpage or look for documentation on your problem.
