If it's really a brand-new disk, I suggest running the manufacturer's disk testing utility to see if the drive could actually be defective. Don't just depend on Open Source tools - the proprietary utilities can often access proprietary, undocumented drive firmware features that are put there specifically for diagnostic purposes, and so do a better job of testing the drive than any Open Source tool could. The problem might just be some bad sectors on your media. If that's the case, the diagnostic utility will remap the bad sectors. If the utility does report bad sector remapping, do a full scan again, and keep repeating until no more bad sectors are found. If you scan more than a couple times and bad sectors are still turning up, your drive is probably beyond repair, and should be RMAed. All the drive manufacturers provide these utilities; go to the manufacturer's website and look either in the Support link, or the Drivers and Downloads link.
