Frequently Asked Questions

External hard-drive recovery begins with a diagnosis, not a scan button. A deleted folder, a RAW volume, and a drive that never appears in Windows need different responses.

Is the External Drive Readable?

If the disk opens normally, check hidden folders, Recycle Bin where applicable, and backups before scanning. If Windows asks to format it or Disk Management marks it RAW, cancel the prompt and preserve the original volume.

If the disk clicks, reports the wrong capacity, or disconnects under light use, stop. Software cannot recover from a device that cannot be read reliably, and repeated scanning may increase wear.

Before You Scan

Check the cable, power supply for desktop units, and a known-good port. Record the disk model and capacity, then ensure there is another disk with room for the recovered data.

Avoid CHKDSK, initialization, formatting, or repair utilities until the files are safe. Such changes may complicate later data recovery.

Scan a Stable External Drive

Qiling Deep Data Recovery provides the scan modes shown below. The mode in Step 2 is chosen for this specific loss scenario; it does not change the need for a separate recovery destination.

Step 1. Protect the Original Drive

Leave the affected drive unchanged and connect a different output disk. Install Deep Data Recovery on the PC's healthy drive.

Step 2. Select the Mode by Cause

Use Fast Scan for recent deletion on a healthy volume, Format Scan after an actual format, or Disk Scan for a stable external HDD with broad file-system loss.

Step 3. Select the Physical External Disk

On the location view, identify the original external HDD by capacity and layout. Confirm the output disk is different before clicking Scan.

Step 4. Preview Important Files First

Filter and preview a sample of high-value documents, photos, and videos. Use Deep Scan only if the device remains stable and the first pass is incomplete.

Step 5. Save Outside the Original Disk

Select verified candidates and click Recover. Save to the separate disk and open several copies before considering any repair to the source.

Choose Repair or Replacement Later

Once the files are secure, test the drive's health. Recurring disconnects or file-system errors mean it should not remain the only place holding important data.

If a scan cannot see a disk that Disk Management also fails to detect, do not infer that a different software brand will solve a hardware or connection failure.

Frequently Asked Questions

Can I use the same external disk as the save destination?

No. A recovery write to the source may overwrite other missing data.

Does a RAW external drive need to be formatted first?

No. Preserve data and scan or image it before making file-system changes.
