Is my hard disk bad?

[nm76]

I turned on my computer today and this error message came up in my event log. 

 

The device, \Device\Harddisk0\DR0, has a bad block.

 

 

So first i checked HDDTUNE test for errors, and no errors, all fields are green. So what can it be? Thx

 

My disk is: Seagate ST1000DM003-9YN162 1TB SATA III 64MB 7200

Download EaseUS partition master and let it run a sector check while you sleep 

 

If you get more than a few bad sectors id say yes

 

Might wanna backup the disk sometime regardless
