Detailed Drive Repair Process

Our drive repair process is designed to prioritize quality, efficiency, and transparency. From receipt to return, each unit follows a clearly defined workflow to ensure precision and consistency in every step. Here’s how we do it:

  1. Unit Receipt & Initial Logging
    • Upon arrival, the drive is entered into our centralized tracking system, which records customer details, unit information, repair notes, and urgency. This information follows the drive through every stage of the repair process.
  2. Repair Number Assignment
    • Each unit is assigned a unique repair number (e.g., SCOL-05232), allowing precise tracking and progress updates throughout the process.
  3. Technician Assignment & Scheduling
    • Our customer service representative (CSR) assigns the repair to a technician with specialized expertise for the brand and type of drive being serviced. The unit is scheduled for teardown at the appropriate service center.
  4. Cost Estimation & Quoting
    • Our costing department identifies the required parts and inputs pricing and availability into the system. The CSR then prepares a repair estimate and sends it to the customer.
  5. Customer Approval
    • The customer approves the repair and provides a purchase order (PO) to authorize the service.
  6. Teardown & Evaluation
    • The drive is disassembled and inspected by a trained technician, who identifies the root cause of failure. Worn, damaged, or high-failure components are noted for replacement.
  7. Failure Analysis & Parts Identification
    • Each failed component is analyzed, and detailed notes are recorded in our tracking system. This data is used to create a failure analysis report, which is later shared with the customer.
  8. Parts Procurement & Assembly Scheduling
    • Once all parts are received, the system notifies our technicians that the unit is ready for assembly. The repair is then scheduled for assembly and testing (AT stage).
  9. Assembly & Testing
    • The drive is reassembled according to OEM standards. It undergoes rigorous functional testing to ensure it operates as intended.
  10. Painting & Final Inspection
    • The drive is cleaned, painted, and prepared for final inspection. The unit is checked to ensure it meets all performance, aesthetic, and safety standards.
  11. Documentation & Reporting
    • The CSR receives a test report documenting the failure analysis, parts used, and test results. This information is included with the unit for customer review.
  12. Packaging & Shipping
    • The unit is packaged to prevent damage during transit and shipped back to the customer. If needed, we offer delivery and pick-up services.
