Ubuntu – What to do if Disk Utility shows bad sectors pending in SMART

hard drivesmart

I have 12.04 32bit installed on my hard drive. Ubuntu is the only OS. I recently installed it after getting rid of Windows 7. When I run Disk Utility under SMART Status it says "disk has a few bad sectors", so I clicked on View SMART data and run self tests. I run the extended SMART self-test and it only takes 5-10 seconds for it to stop and reads Self-Tests: FAILED (Read), Bad Sectors: 1 bad sector, Overall Disk Assessment: Disk has a few bad sectors.

Is this something I should be worried about?

At this point in time I wouldn't. Hard Drive manufacturers, normally pack spare sectors in the drive just for situations like this. Keep an eye on it, and always have a backup of your data handy. Also I would suggest that you run the manufacturers diagnostic tool, and that can be acquired form the drive manufacturers website. Once you do that, and it gives you an error code, and providing htat the drive is still under warranty, then call the manufacturer,and get it replaced.

Important note to keep: Disks that start with 1 bad sector, will probably get worse. I can't stress enough the importance of a backup.
