Abstract: A device includes one or more data storage media having a main storage area, and includes a non-volatile cache memory and a controller. The controller stores a plurality of data packets into a plurality of physical locations in the main storage area. Each of the data packets is associated with a different logical block address (LBA), and each of the physical locations is associated with a different physical location address (PLA). The controller generates mapping information that links the different LBAs to the different PLAs. Upon detecting a soft error when reading a data packet stored in a physical location, the controller relocates the data packet associated with the soft error to a physical location of the non-volatile cache memory. The controller also marks the physical location as a suspect location. The controller updates the mapping information to reflect the relocation of the data packet associated with the soft error.
