ABSTRACT:
In one embodiment, a method for facilitating detection of, and recovery from, data contamination in a non-volatile storage device coupled to an interconnect device includes receiving data to be written to a content area on a non-volatile storage device coupled to an interconnect device, updating a contamination indicator stored in a supplemental area of the non-volatile storage device with a first value indicating potential data contamination in the content area, and transferring the data to the non-volatile storage device for a write to the content area. Further, if a determination is made that the write of the transferred data has completed, the contamination indicator is updated with a second value indicating lack of data contamination in the content area.
