• Residual XML data may remain on disk sectors, depending on storage type (HDD vs. SSD).
• Success depends on whether the medium has been written to after formatting.
• Professional recovery focuses on restoring critical data first, t formulas, t formatting.

Common Causes of Data Loss After Formatting

1. Accidental formatting by the user.
2. System crash or power failure during formatting.
3. TRIM operations on SSDs erasing formatted sectors.
4. Batch formatting multiple files simultaneously.
5. Lack of version control or backup solutions.

Recovery Procedure

Steps to maximize recovery success after formatting: 技王数据恢复

1. Using the Storage Medium: Prevent further writes to avoid overwriting residual data.
2. Create a Backup: Copy the formatted file or disk to a safe location.
3. Professional Recovery Software:
   • Scan storage for residual Excel data fragments.
   • Recover tables, pivot tables, formulas, and charts.
   • Export recovered data to a new workbook for validation.
