IBFirstAID Diagnostician is a tool to recover common corruptions of InterBase and Firebird databases. Two versions of IBFirstAID are available: full-featured Ambulance is intended for diagnose and repair database, and diagnostic-only Diagnostician is intended to check database's health and estimate possible corruptions of databases. IBFirstAID use its own database access layer and doesn't use any InterBase/Firebird software to recover corrupted databases. That is why it can repair database even if it is inaccessible using standard means or if you see critical error like 'Internal gds software consistency check'.
