A method for surveying a data storage subsystem for latent errors before a failing disk drive of the data storage subsystem fails and recovering unreadable data usable to reconstruct data of the failing disk drive. The method includes determining that a disk drive of a plurality of disk drives of the data storage subsystem meets a threshold for being identified as a failing disk drive, and prior to failure of the failing disk drive, surveying at least a portion of the data on the remaining plurality of disk drives to identify data storage areas with latent errors. The identified data storage areas may be reconstructed utilizing, at least in part, data stored on the failing disk drive.
