Fixing soft disk I/O error tool?

[Michael D. Setzer II]

Just did a disk image using dd and compression, and noted that it 
popped up with a few soft i/o errors. Later ran fsck on the 
partitions, and got no errors. What would be the best tool to repair 
these soft errors, or does this mean to replace the disk. I've seen 
no other issues with the disk, and its a little more than 1 year old, 
but less than 2. Its a 1T sata disk.
