When our important data were not tampered with and removed correctly, we have a need to recover and restore data to make the data valid and effective. Usually solve the problem is to remove data set certain data for the log before the operation in the implementation of a modified first data stored in the log, then perform the actual modification operations, the time when errors are found through the rollback operation to restore the original data. Now I share a Data Recovery for Mac with everyone .It is a kind of software that recovers deleted or lost data due to accidental deletion or formatting of HFS, HFS+, HFSX, and FAT file system volumes or corruption of the storage media. Even the data, file from recycle bin or permanently deleted by shift+ delete can be recovered by Data Recovery for Mac. And this also recovers lost/deleted music, video, photo files.
