Repair, I can't help with. But you can check for unique IDs by running a SQL-Select on the primary key, grouping on the count(PK) having count > 1. This will give you a list of duplicate IDs. You can replace the second (or higher) copy of each duplicate with a newly generated key. Unfortunately, if you have child tables you will already have mixed data for two parent records with the same PK. There's no automatic way of cleaning those that I can think of.
