Abstract
A method of managing errors in a plurality of storage drives includes receiving, at a memory controller coupled to at least one storage medium in an SSD, a read command from a host interface. The method also includes retrieving, from the storage medium, read data corresponding to a plurality of data chunks to be retrieved in response to the read command, and determining that at least one data chunk of the plurality of data chunks is unable to be read, the at least one data chunk corresponding to a failed data chunk. And in response to determining the failed data chunk, sending to the host interface the read data including the failed data chunk or excluding the failed data chunk. And in response to the read command sending to the host interface status information about all data chunks.
