Thanks, Alan & Dmitry.

Can anyone tell me WHY this happens? Is Dmitry correct that it is a hardware issue?

Thanks again.

First, don't move the file or try to use it further. Copy it while no
connections to the server are current.
Then check the switches for gbak (ignoring whatever) and try them
If they still don't do anything, your best bet is to make another shell of
the database (make a metadata backup - this should work) and create this
shell. Then use a datapump (several available) to pump the data in all
tables to the new shell.
