Data Recovery Guide
Step-by-step instructions for recovering data from various storage devices
Before You Begin
Stop Using the Device Immediately
Continued use of a failing drive can cause permanent data loss. Power down the device if you notice any warning signs.
Warning: Never attempt DIY recovery if you hear clicking, grinding, or other unusual noises from your drive - this indicates physical damage requiring professional help.
Assess the Situation
Determine whether your data loss is caused by:
- Logical issues (deleted files, formatting, corruption)
- Physical damage (dropped device, water damage, electrical issues)
- Mechanical failure (unusual noises, not spinning up)
Gather Necessary Tools
Depending on your situation, you may need:
- Another computer with sufficient storage space
- USB adapter or external enclosure
- Data recovery software (for logical recoveries only)
- Clean, static-free workspace
Tip: For physical damage cases, professional tools and cleanroom environments are required to prevent further damage.
Device-Specific Recovery Guides
Hard Disk Drive Recovery
Connect the Drive Safely
Use a USB adapter or connect as a secondary drive in another computer. Avoid writing anything to the damaged drive.
Run Diagnostic Tools
Check if the drive is detected in Disk Management (Windows) or Disk Utility (Mac). Note any error messages.
Attempt Data Recovery
For logical recoveries only, use reputable recovery software like:
- Recuva (free, basic recovery)
- R-Studio (advanced features)
- GetDataBack (NTFS/HFS+ specialist)
Note: Always recover data to a different drive, never back to the same damaged drive.
Solid State Drive Recovery
Important: SSD recovery is more complex than HDD recovery due to TRIM and wear-leveling. Success rates decrease significantly after drive use.
Minimize Drive Access
SSDs lose deleted data faster than HDDs. Power down immediately if data is critical.
Check Controller Status
Use manufacturer tools to assess SSD health. Failed controllers often require chip-off recovery.
Professional Assistance
Most SSD failures require specialized tools available only to professional recovery services.
RAID Array Recovery
Critical: Never attempt to rebuild or resync a degraded array without professional guidance.
Document Configuration
Note down RAID level, disk order, stripe size, and any controller settings.
Secure All Drives
Label and safely store all member drives. Never attempt to force a failed drive back online.
Professional Reconstruction
RAID recovery requires specialized software to properly reconstruct the array virtually.
USB Flash Drive Recovery
Check Physical Connections
Try different USB ports and computers. Look for loose connectors or physical damage.
Assess Detection
Check if the drive appears in Disk Management with correct capacity (may show as "RAW").
Recovery Options
For logical issues, use flash-specific recovery tools. For physical damage, professional NAND chip reading may be required.
