I've a program that uses Firebird embeded. On my developer and test PCs always
work well (XP, Vista, 7). On some customers PCs, when the program try to access
the database, appears this message:
Exception class: EIBInterBaseError
Exception message: database file appears corrupt ()
bad checksum
checksum error on database page 425.
The number of the page varies from one customer to other.
I can't understand why this happens, and I can't resolve it. The most
incredible is that the database is not corrupted. I've try it different things,
but nothing resolve it:
1)
- Recreated the database with gbak.
2)
- Extracted all the database (structure and data) on a SQL script.
- Create a new empty database.
- Import the data with SQL script.
3)
- Export the structure on a SQL script.
- Create a new empty database.
- Import the structure from the SQL script.
- Import the database data using IBPump.
The most curious is that if I pass the IBFirstAID, all is OK!
