Are you seeing any offsets in the data? WHat I mean is the data being shifted to the right or left, out of its columns?

I have had that problem moving files accross the network. Sometimes when it happens, the delete flag for that record gets set.

Other than that, I have no idea. I would suspect a user has gotten bored and has started deleting the records.

I have had to hastily write a tool to RECALL the deleted records when they are discovered after a policyholder's enquiry.

For all intent and purpose, we query a vehicle record to find there are no drivers! Of course there are, the pointer records in the junction table have been deleted and have to be recalled.

However, this is done individually and infrequently. We have suddenly been hit with this plague of deleted records in the last 48 hours.
