HP Pavilion Laptop – Accidental Data Deletion & OS Reinstallation Recovery

A client using an HP Pavilion laptop accidentally deleted important data and, in an attempt to fix the issue, reinstalled the operating system (OS). After the reinstall:

  • All previous files were missing, including critical documents, photos, and work-related data.
  • The entire drive appeared overwritten, making standard recovery attempts unsuccessful.
  • The client had no backup, requiring an advanced forensic recovery approach to retrieve lost files.

With 25 years of experience in data recovery, our team was tasked with restoring deleted and overwritten data using the latest forensic techniques.

Our Expertise in Laptop Data Recovery

✔ Recovering lost files after accidental deletion & OS reinstallation
✔ Using forensic recovery tools to extract overwritten data
✔ Reconstructing formatted partitions and lost file structures

Diagnosis & Recovery Process

Upon receiving the HP Pavilion laptop, our engineers performed a forensic-level analysis of the drive. The key findings included:

  • The drive was reformatted during OS reinstallation, making normal access to previous data impossible.
  • Traces of old data remained in unallocated disk space, meaning recovery was possible but complex.
  • Some files were partially overwritten, requiring deep-sector recovery and file reconstruction.

To successfully recover the client’s critical data, we implemented a multi-step forensic recovery process:

Step 1: Disk Imaging & Data Preservation

  • Created a sector-by-sector forensic clone of the laptop’s storage drive to prevent further overwrites.
  • Ensured no further writes to the disk, preserving recoverable data.

Step 2: Deep Data Recovery Scan

  • Used specialised data carving tools to extract deleted files from the unallocated disk space.
  • Identified recoverable documents, media files, and personal data by analysing file headers.

Step 3: File Reconstruction & Partition Recovery

  • Rebuilt fragmented documents and media files that were partially overwritten.
  • Used advanced partition reconstruction techniques to restore lost folder structures.

Step 4: Data Integrity Verification & Secure Transfer

  • Conducted file integrity checks to confirm that recovered files were complete and usable.
  • Successfully transferred all recovered data to an external storage device for the client.

The Result

We successfully recovered over 96.5% of the client’s lost files, including:
✅ Work documents, spreadsheets, and PDFs
✅ Personal photos and multimedia files
✅ Project files and important notes

The client was able to resume work without losing valuable data, despite the accidental deletion and OS reinstallation.
