Anytime the database shuts down without being closed cleanly, there's a chance that it will contain orphan pages, orphan back versions of records, and index entries that don't correspond to a record. The first two problems represent lost space. All three can be fixed by a backup/restore cycle with gbak. Firebird's index handling code will generally ignore incorrect index entries. Problems reported by gbak - either on backup or restore are likely to be actual corruption. Good luck, Ann
