- step 1: Find an identical drive for parts, Model number WD1200JB-00EVA0 and DCM: HSBHNTJCT must match or the heads wont work.
- step 2: The heads are dead, the hard drive probably has micro scratches.
- step 3: The following must be done in a Class 100 Clean Room environment.
- step 4: Replace the Head Stack assembly.
- step 5: Clone the drive with COPYHD.exe from Data Recovery,inc.
- step 6: Start cloning from sector 0 until you reach the first set of Bad Sector(s).
- step 7: Sector 95 and us is important, it contains the FAT (File Allocation Table)
- step 8: Keep track of the location of the bad sector areas, skipping 100,000 sectors or so to avoid damaged areas. Scratches could kill the heads.
- step 9: When you complete the initial cloning process, make a copy of the cloned drive for safe keeping (the original drive could die anytime).
