Abstract
A first data block on a storage device including a data structure of deallocated data blocks on the storage device and a corresponding program erase count value for each of the deallocated data blocks is identified. A determination as to whether a second data block from the data structure of deallocated data blocks remains deallocated after being added to the data structure of deallocated data blocks based on the program erase count value is made. The data is stored at the second data block upon determining that the second data block remains deallocated after being added to the data structure of deallocated data blocks.
