Abstract
Reading data stored at a free block of a storage device is read prior to allocating the free block for storage of data. A determination as to whether a number of bit flips of the data stored at the free block is below a threshold is made. The free block is added to a pool of active free blocks to be allocated for the storage of data upon determining that the number of bit flips of the data stored at the free block is below the threshold.
