File data are corrupt. Archive may be damaged after creation. In this case it is sometimes possible to repair it if it has the recovery record.

It also could have been broken while creating, due to hardware failures (usually caused by an over-clocked CPU or unreliable memory).

In the latter case the recovery record will not help. The only way to detect if the repair will help is to try to apply the repair command to the archive and test the results.
