Easeus Data Recovery Wizard More Other Information

A disk can be formatted in three different ways: Quick, Standard and Low-Level (physical) format. Quick Format enables you to quickly format a disk, by simply initializing the directory entry information in the root directory area and the FAT information. The data area during this proves remains intact.

On the other hand, Standard Format examines the data area, and maps the bad sectors. Since each sector head must be read to determine whether it is bad, the process takes a substantial amount of time. If a bad sector is detected, clusters in that sector are marked in the FAT to prevent them from future usage. However, like quick format, full format does not overwrite the data area, and the data content is preserved.

Finally, Low-Level Format modifies the surface molecule arrangement, initializes the entire disk, and records sector identifiers to each track (creating addresses to identify sectors within each track). All of the data contained in the disk is initialized, preventing any future recovery attempts.

If file system information such as directory entries or FAT is lost, the file cannot be opened by the Windows operating system. However, Data Recovery Wizard is capable of directly reading data from the data area to recover files after a quick or standard format.

For hard disks, a quick or standard format is generally carried out as a high-level format, where data areas are not overwritten. Therefore, even though the FAT or the root directory are initialized, Data Recovery Wizard can still recover the data remaining in the data area.

On the other hand, for disk media that cannot be partitioned with FDISK, such as a floppy disk, a standard format is comparable to a low-level (physical) format process, rendering the original data on the floppy as unrecoverable.

In some cases, files recovered by using Data Recovery Wizard cannot be opened properly. The Microsoft Office (Excel, Word, Power Point) files and large files such as MPEG files often run into this problem. Please consider the following points:

The Damaged Files: After a file is deleted, it could be damaged by another file, overwriting, disk defragmentation, virus attack, or hacking activity. (Microsoft Office files are especially susceptible.)

The Fragmented Files: Some large files are saved in discrete locations because they cannot secure contiguous hard disk space. When one of these files is deleted

Files deleted from a floppy disk can be recovered. Files saved in subfolders, rather than in the root directory, have a higher recovery rate. You can also recover files after formatting a floppy disk. However, you can only recover data if the floppy disk is quick-formatted. Unlike a hard disk, data cannot be recovered after a standard format has been performed on a floppy.

Files that were saved in sub-directories of a quick-formatted floppy disk can be recovered from [Lost Files], whereas ones in the root directory must be restored from [Raw Files].

Normally you can recover intact partitions with the Partition Table Doctor by rebuilding the partition table. Alternatively, you can extract data rather than fixing the damaged disk using the Data Recovery Wizard to copy data from the deleted partitions to another disk.

Data Recovery Wizard is effective against viruses such as CIH, that initialize the file system information including MBR and FAT. Furthermore, Data Recovery Wizard can recover data attacked by viruses that alter the directory entry information such as WormExploreZip. These powerful features are implemented in Data Recovery Wizard - [Lost Files] category. The WormExploreZip virus destroys the entire directory information and FATs, thus completely eliminating file information, extension, and file size data. Consequently, only the data area remains unaffected. Even in these extreme cases, Data Recovery Wizard provides a miraculous recovery result. Data Recovery Wizard cannot recover data damaged by viruses that directly attack a file data area.
