If during the testing of your hard drive DFT reports an error code of 0x70, this indicates that your hard disk drive has problems reading one or more of its sectors. In most of these cases the drive can heal itself of these errors.

To do this first back-up all your data from the problem drive ( if possible ) then run DFT again and select either the Erase Disk or Sector Repair option from the Utilities. If you already have a backup of the data on the hard disk or the data isn't important you can opt to run Erase Disk or Sector Repair from the Test Result screen. Once the selected operation has completed you can then run one of the test options Quick or Advance to confirm that the drive has been healed. The result code, which should be displayed, is 0x00 if the test returns another code then you should check with your drive/system vendor if the drive can be returned for warranty replacement.
