ABSTRACT:
A system and method are provided for avoiding categorization of non-error events as actual error events. This is accomplished by categorizing potential error events as actual error events or non-error events based on a proximity to a physical layer signal state change. By this feature, the result of the categorization may be used to more effectively avoid categorizing non-error events and accompanying noise, etc., as actual error events. To this end, in various embodiments, more accurate error counting is afforded to preclude inadvertent disabling, etc. of a mass storage device or associated link that would otherwise result from a flawed error count.
