Hi Mark, Sorry for the late reply
I did what you said, but impossible to recover the record. The record is not visible even with a full scan and after have drop the index I used the tool IBSurgeon and nothing, the record seems definitively lost. My database is on Force Write Off, may the cause of the problem ... This week I had exactly the same problem on an other database ! The same record was lost. In my application one field of this record is frequently updated (on each operation in fact), Without it my application can't start, so I think to move this field in an other table, but I think the problem will not be solved with this ... just moved (I will set Force Write On too) Thank you for your help Eric
