Repair is a bad idea. As Paul gave a talk last year at TechEd and walked through what happens. Basically they have no idea how to fix things and they start making guesses. He didn't recommend the allow_data_loss.

You''d be better off calling PSS and having them help you get the data out and rebuild the table.

At this point, I'd run some rowcounts and try to determine if you've lost data and perhaps just call PSS. If you have Technet or MSDN, you have some free incidents. If not, buy TechNet ($349) and you get two incidents (normally $249)
