Power Data Recovery - Deleted File Recovery : Volume Recovery : Physical Device Recovery |
Product Overview
Power Data
Recovery is a risk-free and READ ONLY
data recovery utility that helps you in recovering your all important data lost
after accidental format, virus problems, software malfunction, file/directory
deletion, or even a sabotage! It is an easy to use data recovery utility
that examines your inaccessible hard drives for damages and corruptions and
recovers the data back.

Volume, Mirror Volume, Raid-5 Volume.
-
Ability to resume the last recovery
result.
File
System Supported:
-
FAT12,
FAT16, FAT32, VFAT, NTFS and NTFS5 File system.
System Requirements:
Limitations:
-
This software is NOT
able to find data on a physically damaged drive!
-
Not every file can
be undeleted: less fragmentation (common if media not full) will increase
the rate of recovery because the entire data is stored at the beginning of
the first cluster of a file. The probability of recovery is lower, the
smaller the disk capacity relative to the file size is.
Choose "Deleted File Recovery" if you want to recover files that were intentionally (or accidentally) deleted.
Choose "Volume Recovery" if you want to recover files on the re-format or damaged volume.
Choose "Resume Recovery" if you want to resume the last recovery result.
If you have lost partition or cannot find the volume you want to recovery in "Volume Recovery" module, you should choose "Physical Device Recovery".
This module works only with deleted files and allows to "undelete" them (another popular term is "unerase").
Intact file system is important for this module. If you know that there is something wrong with your file system (for example, you did not delete some folder/files but you cannot access them) or if you see something strange with Windows, you should use
"Volume Recovery" module.
First of all, you can see the list of all logical volumes found on Host Computer:
(If you cannot find the volume that you want to recover, please use "Physical
Device Recovery" Module instead.)
Choose one of them and press the "Recover" button.
Then Power Data Recovery will read the file system of the selected volume to
memory.
This step may take a few minutes depending on the size of the used volume space. You have to wait until this scanning is finished, otherwise
Power Data Recovery may not be able to find and recover deleted files. After this scanning is finished, you'll see some progress bars -
Building virtual file system in memory.
After this scanning is finished, you'll see file/folder tree.
Go to "Working with found data" section of this guide for further steps.
This module works with formatted, damaged and
inaccessible volume.
The Volume Recovery module will allow you to recover files from a partition, which has been accidentally formatted or damaged. This type of recovery will scan the specified volume and then list the
analyzed file system. After finished scanning, you just need choose a file
system you want recover.
For example, you did not delete some folder/files but you cannot access them. The file data is still present on the partition and can be recovered using this module.
The first screen on the Volume Recovery module will display a list of volumes found on the system. If the volume that that you want to recover is not listed, you may need to select the
"Physical Device Recovery" module to recover your data.
To start the Volume Recovery module, select a volume and click "Recover" to begin Scanning for
file system.
Power Data Recovery will analyze all the files that the volume included, this may take a few minutes depending on the
capacity of the device.
After the process of analyzing is completed, the Power Data Recovery workspace will display a list of
analyzed file
system.
Once you have identified the file system from which you want to recover data, select the
file
system then press Show Files to begin reading for files.
After reading for files is finished, you'll see file/folder tree.
Go to "Working with found data" section of this guide for further steps.
This module is designed for data recovery from
physical device with crashed file system, mistakenly deleted partitions, drives with failed operation/file system, drives suffered from virus. And if, you want to recover deleted files, you have to choose
"Deleted File Recovery" or
"Volume Recovery". And this module cannot recover data from a Striped Volume, Spanned Volume, RAID 5 Volume.
First of all, you will see list of physical devices attached to Host Computer and partitions
found.If you do not see your Bad Device here, your HDD most probably has some problems
on physical level. We recommend that you send the device to the professional
data recovery company to recover your data.
Then, you have to select the physical device which you want to recover data. Then press Recover to begin scan partitions on the selected device. Power Data Recovery will search all the partition that the device included, this may take a few minutes depending on the
capacity of the device.
After the process of searching partition is completed, the Power Data Recovery workspace will display a list of found partitions.
Once you have identified the partition from which you want to recover data, select the partition then press Show Files to begin reading for files.
After reading for files is finished, you'll see file/folder tree.
Go to "Working with found data" section of this guide for further steps.
Working with Power Data Recovery's file/folder tree is simple - you can walk thru the
tree in the left pane, seeing files in the right pane, with the name, size, date and time.
Main goal here is to select all files and folders you want to recover.
Maximize the Power Data Recovery application window now, in order to see more details
on files and folders you are going to recover.
Open folder trees by clicking the plus signs to the left of folder names in the
left pane. Select a folder in the left pane, and its content will be shown in the right
pane. All columns in the right pane are resizeable (use your mouse on header of columns area). Headers of columns are clickable, you can change sorting order for the list of
files by clicking header of the column.
You have the ability to filter files by selecting the Apply Filter button. By using filter options, you have the ability to view only those specific files you wish to view.
You can find for files with Find File buttons on the right panel of the Power Data Recovery application window.
In Deleted File Recovery module, only the deleted and lost files will be listed in the file/folder tree.
File Preview
Click "View as Text" will display the file content as text (only support .txt and .rtf file.).
Click "View as Image" will display the file as a image (support .bmp, .gif, .emf, .jpg, .tif, or .png and etc.).
Click "View as Video/Audio" will play a video or audio file (all files are supported if a proper codec is installed on the system).
The "Quick Previewer" supports image file and Microsoft Office Word Document,
Microsoft Office Excel file, Microsoft Office PowerPoint file and Adobe PDF
file.
NOTE:
The "Quick Previewer" could display the first page of Microsoft Office
Word Document, Microsoft Office Excel file, Microsoft Office PowerPoint file and
Adobe PDF file only.

Q: Can
Power Data Recovery harm my disk?
As long as
the drive is not physically damaged there is no risk in using the software.
Power Data Recovery only reads from the drive, and does NOT write to it at any
time by itself.
Q:
Can fragmentation of the drive affect the result of the recovery?
Fragmentation
in NTFS should not effect the results of the recovery. Information about a
file's allocation is stored in a MFT entry. However with the FAT file system,
this information is stored in the FAT and this information will be lost after
deleting, so the lower the fragmentation of the drive is, the higher the
chance of a recovery is.
Q: Can I
recover data on a Flash Card™ or SmartMedia™?
Yes,
that's possible, but your media has to be appear as a logical Windows drive.
Look at you camera manufacturer if it supports a special driver software that
will show the smart media as a logical Windows drive. If no driver is
supported you can buy a memory card reader. There are several types: for
notebooks (PC-CARD / PCMCIA) and for PCs (USB, IDE). Ask your local computer
shop!
Q:
Can I recover my data after performing FDISK?
Even if
your partitions have been deleted with FDISK, you can use Physical Device
Recovery and select a physical drive scan from Power Data Recovery 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 Power Data Recovery.
Q: Can I
recover data from a formatted disk?
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 still 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, just 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, Power Data Recovery
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, Power Data Recovery 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
use Power Data Recovery to recover data from CD's, CDR's and DVD's?
No, Power
Data Recovery is a software for hard drives, floppy disks, Jazz drives and Zip
drives only.
Q: Does
Power Data Recovery also recover all NTFS permissions for a deleted file?
No, it
recovers the file information, but the privileges should be re-edited onto the
file.
Q: Does
Power Data Recovery rescue every kind of file format or just some?
Power Data
Recovery can recover all files, but the files may not have been overwritten.
Q: Does
Power Data Recovery run in the background, monitoring your files as you create,
save or delete them? In other words, will it only recover files that were lost
after Power Data Recovery was installed?
The
program does not monitor any files. It get the files by examining the file
system (so called on-disk format of the files). There the files are marked
with special attributes and names. Recovering is simular: the programs scans
the hard disk and searches for a special pattern: the stamp of a directory
('.' or '..') and then assumes a lost directory.
Q: For
what are the recovered .$EFS files?
These
files are packed raw encrypted files that will be imported into a new NTFS
file during saving. If the importing was successful, these files will be
deleted automatically. If the file could not be imported (because it was not
saved to a NTFS volume), you may save your files to a NTFS volume.
Q: I
cannot open the recovered files with software program applicable to the type of
the file recovered. Why?
Your files
were overwritten by other data. In this case there is no way to retrieve the
data.
Q: Is it
possible to recover lost files to a CDR/RW drive?
Power Data
Recovery is not a CDRW burning software! Anyway you can save to a CDRW if the
software/ hardware supports packet recording. You have to install an UDF
driver for your CDRW drive. Then you can save files like to a hard drive to
the CDRW drive (This feature is already included in Windows XP).
HDD
Short for "Hard Disk Drive", an HDD helps manage the transfer of data to and from your computer's hard disk. Because these two items always come as a single unit, "hard disk drive" and "hard disk" are usually used to refer to the same thing.
Partition
A portion of a physical disk that functions as though it were a physically separate disk. After you create a partition, you must format it and assign it a drive letter before you can store data on it.
On basic disks, partitions are known as basic volumes, which include primary partitions and logical drives. On dynamic disks, partitions are known as dynamic volumes, which include simple, striped, spanned, mirrored, and RAID-5 volumes.
Basic Disk
A physical disk that can be accessed by MS-DOS and all Windows-based operating systems. Basic disks can contain up to four primary partitions, or three primary partitions and an extended partition with multiple logical drives.
Dynamic Disk
A physical disk that provides features that basic disks do not, such as support for volumes that span multiple disks. Dynamic disks use a hidden database to track information about dynamic volumes on the disk and other dynamic disks in the computer. When you convert a basic disk to dynamic, all existing basic volumes become dynamic volumes.
Basic Volume
A primary partition or logical drive that resides on a basic disk.
Dynamic Volume
A volume that resides on a dynamic disk. Windows supports five types of dynamic volumes: simple, spanned, striped, mirrored, and RAID-5. A dynamic volume is formatted by using a file system, such as file allocation table (FAT) or NTFS, and has a drive letter assigned to it.
Bad Device
This is the storage device that contains the data you want to recover. A Bad Device can be any disk-like storage media, such as your computer's hard drive, an external
HDD, Flash card or any other form of removable media.
Good Device
This is a storage device that is in perfect working order onto which you want Power Data Recovery to save the data recovered from the Bad Device. The Good Device may be located on the computer on which you've installed Power Data Recovery (the "host" computer). The Good Device can be any of the storage media listed for the Bad Device. The Good Device is used to save recovered data from the Bad Device.
Host Computer
This is the computer on which you have installed Power Data Recovery. The Host Computer is used to recover the lost data from the Bad Device, which should be connected to the Host Computer as an additional drive (second, third or fourth - in addition to the existing
drive(s) on the Host Computer).
The Bad Device set as an additional drive.
If you are using removable media such as a Zip disk or Flash card, you should insert the device prior to launching Power Data Recovery.
FAT
Short for "File Allocation Table", a FAT is a table stored on your storage device that tells the computer where to look over when it needs to find a file stored on this device. When you save data, it is stored in chunks of information called "clusters". The clusters for a single file may actually be located in several different areas on your storage media. The FAT is your computer's way of recording the locations of those clusters for each file you save. The term FAT is often used to refer the file systems, which use File Allocation Tables - FAT12, FAT16, FAT32.
NTFS
Short for "NT file system," this is basically the Windows NT equivalent of the FAT described above.
