Abstract
Data on a storage device may be marked as sensitive data and this marked sensitive automatically destroyed (e.g., scrubbed) upon erasure. For example, when sensitive data is erased, new data may be immediately written over the erased sensitive data. To destroy the erased data, random characters and/or a fixed sequence of characters may be written over the erased data. The storage device, the operating system, and/or other software may share tasks related to tracking and scrubbing sensitive data. Scrubbing may include writing a fixed sequence, such as zeroes, or writing random characters of data.
