Hard Drive Recovery Procedure

  • step 1: Locate an identical drive using the Part Number and/or the Model number, MLC must match H71515
  • The following steps must be performed in a Class 100 Clean Room environment.
  • step 2: Remove and replace the Head Stack Assembly.
  • step 3: The defective should be now operational, unless the platter surface is scratched, duplicate as much of the defective as possible.
  • step 4: Use COPYHD.exe from Data Recovery,inc.
  • step 5: Just in case there are hidden scratches, start cloning the drive from sector 0.
  • step 6: If you should come across a series of Bad Sector(s) prior to sector 6,500,000, start reverse cloning from sector 7,000,00 backward. This will supply you with a copy of the MFT (Master File Table).
  • step 7: If further Bad Sectors are encountered start reverse cloning from the end of the hard drive.
  • step 8: Avoid as many Bad Sector areas as possible jotting down the sector position as you go.
  • step 9: Once you have cloned as much of the hard drive as possible, you can always go back and attack the Bad Sector areas for final refinements.
  • step 10: Make secondary clones of the duplicated hard drive.
  • step 11: If the clone has errors (Bad Sectors), run Data Recovery Software to recover as much data as you can from the clone.
  • step 12: Transfer all files to an external Western Digital Passport USB hard drive.
  • step 13: If the clone has no errors, you should be able to return the clone into active service as if nothing ever happened.
