ntfs HD with io errors

[Ernie Luzar]

Have a 3TB ntfs HD with i/o errors.

ntfs-3g does read it, but a ls command of 2 different directories get 
error msg about i/o errors and nothing is listed.

Is there a way to fsck this HD to fix it?

There is only 600GB of data on the 3TB HD. Looking for way to copy the 
data to a 1TB ufs HD.

What will dump command do with i/o errors?

Can dd command skip over unused space?

Any other ideas?
