摘要:
A storage device may include a data storage portion including a set of blocks designated to store metadata and a controller. The controller may be configured to write first metadata at a first location designated by a first pointer. The first location may reference a block that does not contain any valid metadata. The controller may be configured to determine a number of valid blocks of previously written metadata in a subset of the set of blocks. A first block of the subset may be at a second location designated by a second pointer. The controller may be configured to, if the number of valid blocks is greater than zero, rewrite the valid previously written metadata to a group of one or more sequential blocks.
