Stellar Data Recovery vs Qiling Deep Data Recovery for Windows
Stellar Data Recovery and Qiling Deep Data Recovery both scan Windows drives for lost files. Their published feature sets overlap for ordinary deletion and formatting, while Stellar also documents specific workflows for RAW and BitLocker-encrypted drives. Choose by the condition of your source disk and what the scan can actually preview, not by a promised success percentage.
Match the tool to the loss
| Situation | Stellar Data Recovery | Qiling Deep Data Recovery |
|---|---|---|
| Recently deleted files | Quick or deeper scan, then sort and preview results. | Start with Fast Scan, then inspect filtered results. |
| Files lost after formatting | Scan the formatted volume; use a deeper scan if needed. | Use Format Scan on the original volume. |
| Encrypted or RAW drive | Stellar publishes dedicated support for these cases; BitLocker access still requires credentials. | Check the exact drive state and supported edition before relying on recovery. |
Both vendors let users scan and inspect results, but trial and free recovery allowances vary by edition. Confirm current terms on the product page before purchase. Preview several files that matter to you; a filename in the result list does not establish that its contents are usable.
Encrypted and damaged drives need a different plan
A BitLocker-protected disk cannot be recovered simply by scanning encrypted sectors without the recovery key or password. Check your Microsoft account, organization, or saved key records first. For a drive that repeatedly disconnects, clicks, or reports many read errors, stop ordinary scans and consider professional help or a controlled image-first workflow. Neither program fixes physical damage.
On an SSD, deleted data may be cleared by TRIM. Stop installing software or copying files to the affected SSD as soon as you notice the loss.
How to test recoverability with Qiling
Install the software on another physical disk when possible, and prepare a separate destination for any files you recover.
Step 1. Open Deep Data Recovery. Choose Fast Scan for ordinary recent deletion or Format Scan when files disappeared after formatting. Select another mode only if it matches the actual loss.
Step 2. Locate the original volume by drive letter and size, then click Scan. Do not format or repair it before checking whether the files can be found.
Step 3. Use file filters and preview to inspect a small sample of important documents or photos. If results are incomplete, review the available deeper scan option without writing to the source.
Step 4. Select the usable files, click Recover, and save them to a different physical drive. Open the copies before reusing the original disk.
Which should you use?
For ordinary Windows deletion or formatting, run a non-destructive scan and judge the result by readable previews. If the drive is encrypted, Stellar's documented BitLocker workflow may be relevant, provided you have the credentials. For a physically failing disk, neither DIY application should be your first experiment.
