How We Can Help
When backup fails and the database corrupts, our team springs into action. We use 'Forensic Database Recovery' techniques to extract data directly from file data pages, even when the database engine (SQL Server, Oracle, etc.) cannot attach the file. We recover deleted records, truncated tables, and fix consistency corruption (Page Checksum Error).
Common Symptoms
- Database in 'Suspect' or 'Recovery Pending' mode
- Consistency error (DBCC CHECKDB errors)
- Tables or records disappeared
- Corrupted or lost log file (.LDF)
- Failure to Attach database
- Corruption due to power or hardware failure
- Ransomware encrypted the .MDF/.BAK file
- Accidental Delete or Drop Table

Understand the recovery flow in four steps, from free diagnosis to data delivery.
1. Free Diagnosis
