Proactively refreshing storage zones within a storage device

A computer program product comprising one or more computer readable storage media and program instructions collectively stored on the one or more computer readable storage media, the program instructions executable by a data storage device to cause the data storage device to:

• determine that one or more data quality prediction parameters associated with a storage zone of the data storage device meet a predetermined threshold, wherein the one or more data quality prediction parameters indicate anticipated bit decay within the storage zone;
• and
• initiate a proactive refreshing of the storage zone based on the determining that the one or more data quality prediction parameters meet the predetermined threshold, the proactive refreshing of the storage zone including:
• reading all data in the storage zone;
• determining whether errors have occurred during the reading of the data;
• in response to determining that errors have not occurred, moving the data of the storage zone to a new storage zone;
• and
• in response to determining that errors have occurred, initiating a rebuild of the storage zone, wherein the data is rebuilt in the new storage zone.

A system comprising:

• a processor, a computer readable memory, and one or more computer readable storage media associated with a data storage device;
• program instructions to determine that one or more data quality prediction parameters of a storage zone of the data storage device meet an associated predetermined threshold, wherein the one or more data quality prediction parameters indicate anticipated bit decay of the storage zone;
• and
• program instructions to initiate a proactive refreshing of the storage zone based on the determining that the one or more data quality prediction parameters meet the associated predetermined threshold, the proactive refreshing of the storage zone including:
• reading all data in the storage zone;
• determining whether errors have occurred during the reading of the data;
• in response to determining that errors have not occurred, moving the data of the storage zone to a new storage zone;
• and
• in response to determining that errors have occurred, initiating a rebuild of the storage zone, wherein the data is rebuilt in the new storage zone,
• wherein the program instructions are collectively stored on the one or more computer readable storage media for execution by the processor via the computer readable memory.
