Your drive has mechanical and electronic problems. (2 and 3 below)
3 types of drive-level problems:
|Problem 1||Mechanical problems. Most professional data recovery companies have tools and methods for addressing mechanical problems.|
|Problem 2||Electronic problems. Most professional data recovery companies have only a partial solution for addressing electronic problems.|
|Problem 3||Only the top data recovery companies have the experience and the resources to fix firmware problems.|
The 3D Data Recovery Phases & Issues requires that you complement your current methods with tools and a methodology that consistently diagnoses mechanical and electronic issues and fixes up to 80%-90% of firmware problems.
Hard Drive Diagnostics and Repair:
Phase I of the 3D Data Recovery Phases & Issues.
This phase deals with drives that are not responding, and drives that appear functional and can be imaged, but produce useless data. The solution is to diagnose the drive for damage and make repairs as necessary.
Disk Imaging. Phase 2 deals with creating a clean duplicate of the disk contents on a new disk. This can be used as a stable platform for Phase 3.
This phase deals with drives that have read instability problems and bad sectors or are in danger of failure.
In this phase, the contents of the repaired drive are read and copied to another disk using disk imaging software and hardware. Disk imaging prevents further data loss caused by working with an unstable drive during the subsequent data retrieval phase.
Phase II problems
Most DR companies are using imaging tools that are designed only for use on “good” drives. This approach does not provide maximum data for three reasons:
|Problem 1||The imaging software processes are so intense that they further damage hard drives.|
|Problem 2||The imaging software skips bad sectors and only copies good sectors.|
|Problem 3||The imaging software takes days or weeks to image bad drives.|
Phase 3. Data Retrieval – Phase 3 involves rebuilding the file system, extracting user data and verifying the integrity of the files.
File System Recovery and Data Retrieval:
|Problem 1||They can’t retrieve files because of a corrupt file system.|
|Problem 2||They can’t guarantee the integrity of the files they have recovered.|
|Problem 3||They can’t handle corrupted files that have been retrieved.|
Our Recovery Systems provides tools that address drive-level, disk-level and data-level issues so that the maximum amount of data is retrieved.
Fixing Phase III problems:
Methodology & Tools: We use the recommends the PDR Methodology™ and a number of tools to address the issues that arise in Phase III:
- File system recovery: Corrupted file system structures such as corrupted directories or boot sectors are rebuilt using hardware tools.
- File verification: Recovered files are tested for potential corruption. Our tools provide a file verification tool that generates a report which can be delivered to the client.
- File repair: If necessary, corrupted files are repaired if data could not be fully restored in previous phases, or if corruption has occurred because of partial restoration, disk imaging is repeated to retrieve more sectors.
