    摘要： The disclosure is related to monitoring a portable electronic device to detect an occurrence of a power event. A command can be sent to a data storage device to initiate a maintenance procedure on the data storage device. In a particular embodiment, a method includes monitoring a portable electronic device to detect an occurrence of a power event. The method also includes selectively sending a command to a data storage device to initiate a maintenance procedure on the data storage device when the occurrence of the power event is detected.

    摘要： Minimal and maximal numbers are established defining two levels of retry attempts to read system information from a storage medium. Multiple copies of the system information are stored on the storage medium. Attempts are made to successively read the copies until either the system information is successfully read or the system information is not successfully read from any copy of the system information after the minimal number of attempts on each copy. If the system information is not successfully read, attempts are made to successively read the copies until either the system information is successfully read or the system information is not successfully read from any copy of the system information after the maximal number of attempts.

    摘要： An apparatus and method for selecting physical cylinders (cylinders accessible for read/write operations) in a disc drive is provided. The disc drive includes at least one rotatable disc. The disc drive also includes a first head, which is positionable adjacent a first disc surface, and a second head, which is positionable adjacent a second disc surface. The first disc surface has a first plurality of greycode tracks and the second disc surface has a second plurality of greycode tracks. Each greycode track of the second plurality of greycode tracks corresponds to a different greycode track of the first plurality of greycode tracks, thereby forming a plurality of greycode cylinders, with each greycode cylinder of the plurality of greycode cylinders including a pair of corresponding greycode tracks. The physical cylinders are a subset (less than all) of the plurality of the greycode cylinders. The method of selecting the physical cylinders includes determining whether the first plurality of greycode tracks or the second plurality of greycode tracks demonstrates greater track eccentricity, to thereby obtain a maximum track eccentricity surface and a corresponding maximum eccentricity head. The maximum track eccentricity surface is one of the first and second disc surfaces and the maximum eccentricity head is a corresponding one of the first and second heads. The maximum eccentricity head is used to locate at least one of the physical cylinders.
