This setup is relatively clean, but others may have already suffered from data overwriting or media corruption and damage. Granted I did not extensively test this aspect of the program, so while this recovery was successful, it is always good to keep in mind that success of recovery may depend on your specific drive's setup. Sometimes recovery programs may only recover part of a file, or include junk data that makes the byte counts mismatch and result in them not loading correctly, but that did not appear to happen here.

Recovery of these files was straightforward, and upon saving them to a secondary hard drive, the byte counts for each matched the originals and they displayed properly in numerous programs, indicating the recovery of them was a full success. Both of these scans showed the same results, and only presented the JPEG and JPEG-2000 image types. The program only showed two of the four file types being available for recovery.ĭespite only showing two files as being on the drive, I went ahead and deleted all the files and scanned again followed by performing a format of the filesystem (this time not doing any zeroing of data) and scanning a second time. This is where the program seemed to show its limits, and upon scanning the drive found that of the file files (of which four were supported by the program), only two were detected (JPEG and JPEG-2000). Because files on the filesystem show the same stored data patterns as those that have been deleted, I expected the program would detect them since scanning is done block-by-block instead of by interacting with the disk's index and directory files-as long as the data is there, then the program should detect it. I then copied the files to the drive and scanned the populated filesystem to see if the program would detect the files.

After doing this I ran the software and scanned the drive for files to ensure none was detected, and confirmed the software could not recover any files from the empty filesystem. With the test files prepared, I then fully erased a USB drive with Disk Utility, writing zeros to the surface to ensure no files could be detected by the software. The program did not detect any files on the freshly formatted and zeroed volume.

In addition I converted the image to a PDF format, which, while neither in itself an image format nor one that Stellar's program claims to identify, I threw in anyway to see if it would be recognized during scans.
I decided to do a similar approach with this latest test of Stellar's Photo Recovery package, and attached a USB drive in which I attempted a recovery of four basic image formats (JPEG, JPEG-2000, TIFF, and PNG), which I prepared by taking a standard JPEG file and converting it to these formats using by Apple's Preview application. In my past look at Stellar's Data Recovery software I wrote a single PDF file to an empty drive and deleted it to see if Stellar's software could recover it. Stellar claims that Mac Photo Recovery will identify a number of image formats, including JPEG, TIFF, PNG, GIF, BMP, JP2, INDD, PSD, MOS, PSP, and PCT, so to test the software I decided on setting up a simple and straightforward recovery routine for it. In the past I was unimpressed with the lackluster performance of Stellar Phoenix's "Data Recovery" suite for OS X, but found that after using Photo Recovery that despite a few limitations it, for the most part, appeared to do its job. The program supports recovering files from both local disks as well as from a variety of cameras. Recently Stellar Phoenix released a new version of its Mac Photo Recovery software (version 4.0), which is a $39 file recovery utility tailored toward identifying deleted and lost media files on disks, including a number of image, video, and audio formats.
