Q: Can I recover data from a formatted disk?
A: 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 to be
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, just like quick format, full format does
not overwrite the data area, and the data content is
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
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.
Q: Can I recover my data after performing FDISK,
Pqmagic or Super Fdisk?
A: Even if your partitions have been deleted with
FDISK, you can use AdvancedRecovery and select a
physical drive scan from Data Recovery Wizard
and recover the data from the lost partition.
Furthermore, even if you have created new partitions
after removing the old ones, you can still recover
your data with the Data Recovery Wizard.
Q: What kinds of viruses are protected against by
the Data Recovery Wizard counter measures?
A: 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's [Raw 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
Data Recovery Wizard cannot recover data damaged by
viruses that directly attack a file data area.
Q: I have recovered a file, but I cannot open it.
A: In some cases, files recovered by using
Data Recovery Wizard cannot be opened properly.
Microsoft Office (Excel, Word, Power Point) files
and large files such as MPEG files often run into
this problem. Please consider the following points:
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)
Some large files are saved in discrete locations
because they cannot secure contiguous hard disk
space. When one of these files is deleted, recovery
can be very difficult. Even though the file's start
location is available, the location information of
other fragments is usually erased.
Q: Can I recover files deleted from a floppy
A: 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].
