Abstract: The present invention provides a data recovery method for EXT2 file system without pre-installing an additional program and a computer readable storage medium storing the data recovery program. The method includes extracting partition table from a storage medium stored data to be recovered, extracting entries of directories and files from a partition using the extracted partition table, extracting the data corresponding to the entries, and combining the extracted data so as to be stored as a new file, whereby it is possible to recover the files damaged or deleted without the previously installed additional program.
