File Recovery Performance Detailed Results

Below are the results of the data recovery tests we performed with each of the software candidates. These tests were designed to recreate the most common data recovery scenarios faced by professionals. In each test, the operating system was Windows 7 32-bit.

For each test, the same set of test files were deleted from the disk. In instances where the file system was damaged or a partition was deleted, the files listed below were present on the disk prior to the damage or repartitioning.

Test File Set

File Type File Extension
Archives rar, zip
Audio files acc, mp3
Documents doc, docx, xls, xlsx, odt, ods, pdf, txt
Video files flv, mp4, mpg, avi, m4v
Images jpg, png, tiff
Programs exe

RAID Recovery

To test data recovery from a RAID, we deleted test files from the list below using various RAID level configurations.

Product Rating RAID 0 (2 Disks)
R-Studio 5.5 All files were found in their original folders with original names and successfully recovered after disk scan.
Restorer Ultimate 5.5
UFS Explorer Professional Recovery 3 Files could only be found using IntelliRAW (using file signatures). The file and folder names couldn’t be recovered.
GetDataBack + RAID Reconstructor + Captain Nemo 6 Correct RAID 0 parameters were automatically found. All files were found in the original folders with original names and successfully recovered after disk scan.
DMDE 5.5 All files were found in the original folders with original names and successfully recovered after disk scan.
All programs, except UFS Explorer, were able to find all files in their original folders with original names and successfully recover them after disk scan. UFS Explorer could find files only using file signatures, that is, without file and folder names. The GetDataBack package automatically found the correct RAID 0 parameters; the other programs do not have this feature for RAID 0.
Product Rating RAID 5 (3 Disks)
R-Studio 5.5 Correct RAID 5 parameters were not found automatically. All files were found in their original folders with original names and successfully recovered after disk scan.
Restorer Ultimate 5.5 All files were found in their original folders with original names and successfully recovered after disk scan.
UFS Explorer Professional Recovery 4.5 Most (not all) files were found in their original folders with original names and successfully recovered after disk scan.
GetDataBack + RAID Reconstructor + Captain Nemo 3 Correct RAID 5 parameters were not found automatically. Although the folder structure could be determined correctly, there were no files in respective folders. Some files could be found in Lost Files (using file signatures), but many of them could not be recovered correctly.
DMDE 1 Although the folder structure could be determined correctly after disk scan and files were found in them, those files appeared damaged.
All programs, except the GetDataBack package and DMDE, were able to find all files in their original folders with original names and successfully recover them after disk scan. The GetDataBack package could find some files only using file signatures (without file and folder names recovered). Neither R-Studio nor the GetDataBack package were able to automatically find the correct parameters for the tested RAID 5. It should be noted, however, that both these programs did find correct RAID parameters in other tests (see “Automatic RAID Parameter Detection” in the Features and Interface Detailed Results section).
