Software used to recover data in Linux from hard drives can assist in recovering files when there has been a loss of data because of accidental deletion or when there are problems with the partitions or filesystem of the hard drive. It is important that you select software that supports the specific filesystem and storage device used in your case. It is advised not to save any other files on the same hard drive before performing the scan since this might lead to further erasure of data. Deep scans will take a long time in cases where large drives are involved, but they will enable you to recover some files that might have been missed by quick scans. You need to save the recovered files on another working drive because a bad drive might lead to extra stress on the hard drive.
