Abstract
A block-level data storage system receives a request to delete a data storage volume. As a result, the data storage volume is deleted and the areas comprising the volume are released and reaped. The areas may contain non-zero data within a plurality of data storage chunks that comprise the areas. An area cleaner is configured to zero out the areas for allocation to a newly created data storage volume.
