When I compare md5sums of the file a.fdb on both OSes, and they are exactly the same. This was one of the first things I tried...

My top suspicion is that you have a backup file there that you have inadvertently named with the ."fdb" extension. I suggest you try again, this time just making certain about those file names when you back up and restore. BTW, this error has nothing to do with the file name: it is raised when the engine finds the named file but can't find a database header page in it. Also, Firebird doesn't care about extensions at all. ".fdb" for databases and ".fbk" for backup files are just a convention. Helen -- /Da Capo/
