Partition loss

Recovering data from partition loss means retrieving files from a drive where a partition has been deleted, lost, or is no longer accessible. This can happen due to accidental deletion, formatting, OS errors, or malware. Here’s how to handle it step by step:

What Is Partition Loss?

A partition is a logical division of a disk. If it's lost or corrupted:

  • The drive might appear as "unallocated" or "RAW".
  • The partition may simply be missing from file explorers or disk management tools.

Steps to Recover Data After Partition Loss

Stop Writing to the Drive

Do not format or create a new partition. Writing new data may overwrite the lost partition and make recovery impossible.

Use Partition Recovery Software

Several tools can scan the disk for lost partitions and recover the data:

Recommended Tools:

  • TestDisk *(free & powerful)* – Recovers lost partitions and rebuilds partition tables.
  • MiniTool Partition Wizard
  • EaseUS Partition Recovery
  • AOMEI Partition Assistant
  • R-Studio *(advanced, paid)*

Basic Recovery with TestDisk:

  1. Run TestDisk as administrator.
  2. Select the affected disk.
  3. Choose “Analyse” to search for lost partitions.
  4. If found, select and write the partition table.
  5. Reboot and access your data.

Recover Files Without Rebuilding the Partition (Optional)

If partition repair fails or is risky:

  • Use tools like PhotoRec, Recuva, or Disk Drill to scan the entire drive (sector-by-sector) and recover files directly.

Don't Format or Initialize When Prompted

Windows and macOS may ask to format the drive—**decline it until recovery is complete.

Prevent Partition Loss in the Future

  • Always back up your system image or key partitions.
  • Avoid unsafe shutdowns and power loss.
  • Use disk partition tools carefully.
