Abstract

Systems and techniques are described for transferring data. A described technique includes receiving a request to transmit a data block from a first data storage device to a second data storage device. An attempt to read the data block from the first data storage device is made. A media error resulting from the attempt to read the data block from the first data storage device is detected. In response to detecting the media error, a new data block is generated and includes mismatched checksum data that causes a checksum mismatched error when the new data block is accessed. The new data block is transmitted for storage at the second data storage device in place of the data block.
