Hi,
I gather that the primary ID is the first field in the record, if so add an 8 character dummy field as the first field in the record.

This doesn,t fix the problem, as the dummy field gets the corruption not the primary index. There was an article about this some time ago.

And it means that every day programmer find in the table _several_ rows with the same ID=0 (or ID=3) – the purpose of primary key is not work. Transaction mechanism was not help.
