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.

Claim (Index 8):
A system comprising:\n a data processing apparatus; and a memory apparatus in data communication with the data processing apparatus and storing instructions executable by the data processing apparatus and that upon such execution cause the data processing apparatus to perform operations comprising:\n receiving a request to copy a replica of an object from a first host to a second host, wherein the first host stores data of the replica of the object in a set of data blocks; \n for each of a plurality of subsets of the set of data blocks, determining whether the subset of data blocks has a media error by attempting to read the subset of data blocks; \n for each subset of data blocks that does not have a media error, copying the subset of data blocks from the first host to the second host; \n for each subset of data blocks that has a media error:\n identifying, in the subset of data blocks, each data block that has a media error; \n generating, for each identified data block, a new data block including mismatched checksum data that causes a checksum mismatched error when the new data block is accessed; and \n copying, to the second host, (i) each data block of the subset of data blocks that does not have a media error and (ii) the new data block generated for each identified data block.
