Abstract
In some examples, there is provided a method for a storage controller to receive a request to write data at a virtual location, writing data at the next free physical location in sequence, writing metadata correlating the virtual location with the physical location at the physical location, and writing a counter at the physical location. The recorded metadata can be used to re-construct the mapping between a given physical location and its corresponding virtual location if the virtual block address is somehow lost. The recorded counter can be used to determine the most recently recorded mapping between the virtual location and physical location, thereby resolving any discrepancies between earlier recorded metadata.
