Abstract
A datastore, such as a registry or file system having a defined data structure with a logical layer, may be analyzed using a bitmap corresponding to equally sized blocks of data in the datastore. The bitmap is created by traversing the datastore and setting a bit at the beginning of each cell of data, where one cell may have multiple blocks. The datastore is traversed again at a logical layer to verify that each cell is used only one time. The second traverse may unset the beginning bit of each cell as the cell is used. An inconsistency is detected in the datastore when a bit is already unset during the second traverse and when set bits exist after the second traverse.
