Error: This database cannot be read due to an invalid disk structure

I am trying to open a user's archive file and receiving "this database cannot be read due to an invalid on disk structure". I'm using R5, have tried various fixes listed in this forum and am still at a loss. Any ideas?
Sometimes DBs cannot be fixed. If you have tried compact , fixup, & updall and nothing works, you may be out of luck. Try making an OS copy to another drive, or pull it up on a server. Good luck.
