Asynchronous raid stripe writes to enable response to media errors

A computer program product including computer usable program code embodied on a nontransitory computer readable storage medium for handling media errors, the computer program product including:

• computer usable program code for detecting that a first file and a second file are duplicates;
• computer usable program code for copying a first previously stored segment of the first file from a second storage device to a target storage device so that all of the first file is stored on the target storage device
• computer usable program code for storing the second file to the target storage device;
• computer usable program code for writing metadata to the target storage device in association with the first file, wherein the metadata associated with the first file identifies the location of the second file;
• computer usable program code for responding to a media error that results from a first read operation to read the first file including reading the metadata associated with the first file to identify the location of the second file, performing a second read operation to read the second file instead of the first file, and providing the second file in satisfaction of the requested first read operation.
