chunk of lost data
Description of the issue
I have recently lost a large chunk of data. To be precise 641 pages out of the 3600 in our database. I am using Filemaker along with 2 other people. One logs on, the other two log on as guests. For a few weeks now, when the first person logs on a window pops up saying "looking for unused blocks"(rough translation from French "Recherche de blocs inutilisés") and it takes a good 2-3 minutes to open.
We have now noticed that pages are missing. When I go to find a page, the page appears but totally blank. It seems as if the page is masked, or the information hidden. The page also seems to be blocked, I can't enter any further data onto the blank pages, whereas I can still enter data onto pages showing data. The data must still exist, otherwise no corresponding page would show up. Any ideas?
Exact text of any error message(s) that appear
"Recherche de blocs inutilisés"
