Abstract
Partitions of drives are used to form a volume of a drive array. Each partition is associated with a trusted computing group (TCG) band. Each drive encrypts data stored on the partition with a key unique to the TCG band. The volume is formed using the partitions of the drives. In response to a band-based erasure being invoked on the volume, each drive of the plurality of drives overwrites the key of the TCG band associated with the partition and provides an erasure certificate attesting to the overwriting of the key. The erasure certifications from the drives are compiled into a consolidated erasure certification that attests to the erasure of the volume.
