[firebird-support] Unable to repair a corrupt database

[cyc...@gmail.com [firebird-support]]

I have a Firebird 2.5.2 database (ODS 11.2).  The database has corrupted.  When 
I open the database, I receive a message 
 page 1577 is of wrong type (expected 4, found 5)
 I have tried using gfix, gfix -mend, gbak to attempt backup but it doesn't 
work.  I also try if qli may extract the data, and again, I can't open the 
database in ready statement.  Same corrupt message prompt out.
 

 I even try to change the byte at position (1577 * 4096) from 0x05 to 0x04 but 
it turn out to the following message when I perform gfix or gbak:
 Reached the end of the file.
 I think IBSurgeon shall works but the price isn't something I can afford.  Is 
there any other alternate way to fix the database?

Hi,

Try to open database with FirstAID Extractor (it's free) and check is 
there data you are looking inside.
