Abstract
Systems and methods are provided that may be used to identify and report multiple information units (e.g., logical blocks) having medium errors within a given composite information structure (e.g., physical block) of a storage device (e.g., such as a hard drive) whenever any single information unit having an error within the same composite information structure is accessed.
Claims20
An information handling system, comprising:
- at least one storage device including storage media;
- at least one first processing device coupled to the storage device and configured to access the storage media for reading and writing data on the storage media as individual composite information structures having a first data size, and to provide data read from the storage media and to accept data for writing to the storage media as emulated information units having a second size, the second data size being smaller than the first data size such that each composite information structure is subdivided into multiple smaller emulated information units;
- and
- one or more second processing devices coupled to the first storage device and configured to provide data to the first processing device for writing as the emulated information units, and to accept read data from the first processing device as emulated information units;
- where the first processing device is further configured to detect the identity of multiple emulated information units having storage medium errors within a given composite information structure during a given access to the given composite information structure for input/output (I/O) operations on one or more of the emulated information units, and to then report the identity of the multiple detected emulated information units having medium errors within the same accessed composite information structure at the same time to the second processing devices.

A method for operating a storage device that includes storage media, comprising:
- using at least one first processing device to access the storage media of the storage device for reading and writing data on the storage media as individual composite information structures having a first data size, and to provide data read from the storage media and to accept data for writing to the storage media as emulated information units having a second size, the second data size being smaller than the first data size such that each composite information structure is subdivided into multiple smaller emulated information units;
- using one or more second processing devices to provide data to the first processing device for writing as the emulated information units, and to accept read data from the first processing device as emulated information units;
- and
- using the first processing device to detect the identity of multiple emulated information units having storage medium errors within a given composite information structure during a given access to the given composite information structure for input/output (I/O) operations on one or more of the emulated information units, and to then report the identity of the multiple detected emulated information units having medium errors within the same accessed composite information structure at the same time to the second processing devices.
