Abstract
In general, a storage device may perform an incremental background media scan. The storage device includes a data storage portion comprising a plurality of blocks. The storage device also includes a controller configured to perform the scan to determine whether to perform maintenance on the page. As such, the controller may scan a first page of a first block of a set of blocks. Each block has multiple pages. The controller may, for each respective remaining block of the set, scan a respective first page of the respective remaining block, the first page having a same first index as the respective first page. The controller may further scan a second page of the first block. The controller may then, for each respective remaining block of the set, scan a respective second page of the respective remaining block, the second page having a same second index as the respective second page.
