Subject From IB 5.6 to FB 1.5 then back to IB 5.6: ISC Error 335544379--How to fix?
Author Chuck Belanger

I moved a Interbase 5.6 database over to another computer which has
Firebird 1.5 on it and worked on it there, adding about 15,000 records
to a particular table. Then I moved it back to the computer with IB on
it and it seems that FB did something to the database that IB has
problems with:

ISC Error: 335544379 Unsupported on-disk structure for file. Found 10 s
(and it stopped there)

Is this something I can correct? How?

Thank you,
