Hi,

Are you saying Gfix gives you the page error, or after running it you
get the second error message when your app tries to log in?

We've found that sometimes running gfix repeatedly can help, as if the
first pass through has made it possible for later runs to fix more
problems.

We've also found that often DB corruption is due to a disk error, and
running scandisk reveals that the database is cross-linked with
another file somewhere. We only get that on FAT32 OSes though (win98
or 98SE/ME).

It could just be irretrievable though. Normally you can get them back
to life, but on occasion there's nothing to be done, and you just have
to resort to the most recent backup.

HTH.
