Boot up with a live cd/usb and fsck your partitions
sudo fsck /dev/sda1
Replace sda1 with whatever applicable.

How many? It's normal for new disk to have bad sectors.
If it has a green check mark then it should be within acceptable limits.
If the count is going up quickly then you may need to contact the manufacture of your drive and make good on it's warranty if it has one.

It's normal for new disk to have bad sectors.
Weellll, yes, but your OS should never find them because the manufacturer should have blocked them.
OP: Use the manufacturer's diagnostics to test the drive. You'll most likely have to do that to get it replaced under warranty anyway.

Personnally, I wouldn't trust Disk Utility to flag bad sectors.
Much better approach is what others have suggested -- get disk test utility from the drive manufacturer and run that.
And, BTW, with new disks, you should NOT be seeing any bad sectors. They should have already been flagged and removed.

I guess you guys are right, I had assumed smart would just ask the drive what it's bad sector count was and the drive would give it.
I guess it only reports re-mapped sectors. I just looked at mine (1 year old) and it has zero so I would be concerned about your disk as well.

fsck.ext4 -c /dev/sda1

i had a similar problem.
if you think something is not right with your HDD and you have nothing important or can make a backup of ur data, i suggest make your HDD somewhat as good as new by completely erasing everything including partitions with Active Killdisk from killdisk.com
worked for me...
