Overview
Data recovery software all makes the same promise, and the difference between packages comes down to how deep the scan goes and how much of the original file structure survives it. Stellar does a quick scan first, which reads the file table and returns anything that was simply deleted, then a deep scan that walks the raw sectors looking for file signatures when the table itself is gone.
The deep scan is where the useful work happens. A formatted volume, a corrupted partition table, a drive that suddenly reports as unallocated, or a card that a camera decided to reinitialise, all of these leave the data on the platters or the flash while destroying the index that points at it. Signature scanning finds the files by their headers and rebuilds them with a generic name, which is not pretty but is a great deal better than losing them.
Three configurations ship in this package. Professional handles deleted files, formatted drives and lost partitions. Premium adds repair for damaged photo and video files, which is a genuinely separate problem from recovering them. Technician adds RAID reconstruction for arrays whose controller has failed, along with the ability to build a bootable recovery drive so a machine that will not start can still be worked on.
What it does well
Quick and deep scanning
A fast file table pass for straightforward deletions, and a raw signature scan for formatted, corrupted or reinitialised volumes.
Preview before recovery
Documents, images and video preview inside the results list, so you can confirm a file is intact before spending disk space on it.
Photo and video repair
The Premium configuration repairs damaged media files, using a known good sample from the same camera as a reference where one is available.
RAID reconstruction
The Technician configuration rebuilds RAID 0, 5 and 6 arrays in software when the controller is the part that failed.
Bootable recovery media
Build a recovery drive to work on a system that will not start, without installing anything onto the failing disk.

- Signature set extended to more current camera raw and video formats.
- Video repair improved on files truncated by a card removal mid-write.
- Scan sessions can now be saved and resumed rather than restarted.
- Fixed a crash when scanning drives with an unreadable sector range.

Installation
- Install onto a different drive than the one you are recovering from.
- Extract the archive and run setup.
- Apply the included configuration step and pick the edition you need.
- Select the source drive and start with a quick scan before a deep one.
- Recover to a separate destination drive, never back onto the source.
Before you start
Writing anything to the affected drive reduces what can be recovered, stop using it immediately.
A deep scan on a multi-terabyte drive can run for many hours, save the session so it can be resumed.
Recovered files from a signature scan lose their original names, sorting by type and preview is the way through them.
Questions about this title
Can it recover from a formatted drive?
Often yes, through the deep signature scan, as long as nothing has been written since.
What is the difference between the editions?
Professional recovers, Premium adds media repair, Technician adds RAID reconstruction and bootable media.
Does it work on a drive that will not boot?
Yes, build the recovery media and run the scan from there.
Can I recover onto the same drive?
No. Always recover to a different destination or you overwrite what you are trying to save.
About this listing
This entry was checked on a clean install of Windows 7 / 8 / 10 / 11 (64-bit) before it was published, and it is rechecked whenever the package is rebuilt. The figures on this page come from the site index rather than from the publisher, so the download count is what people here have actually pulled.
If a mirror stops answering, use the contact form and it gets replaced. Reports about a specific title are handled faster than general messages because they name the file, the mirror and the point at which the transfer stopped.
Requests for a different version, a different language build or an older release go on the requests page. Older versions of a title are usually still held even when only the current one is listed.
