Abstract
Searching for patterns stored on a hardware storage device. A method includes, as part of a memory refresh operation, performing a read to read contents of a portion of a memory. The method further includes writing the read contents of the portion of memory back to the portion of memory. The read contents are provided to data comparison logic. Using the data comparison logic; the read contents are compared to predetermined data patterns. A determination is made as to whether or not the contents match at least one of the predetermined data patterns. When the read contents match at least one of the predetermined data patterns, a software readable indicator is provided indicating that the read contents match at least one of the predetermined data patterns. Similar embodiments may be implemented using hard drive head wear leveling operations.
