Frequently Asked Questions

External SSD recovery differs from an external hard disk. If deleted blocks have been discarded by TRIM, a deeper scan may not recover them. Start with intact copies and keep writes to the SSD to a minimum.

Check the SSD and Its Copies

Confirm Windows detects the device at its expected capacity. Try a known-good cable or port once if the connection is unstable, but avoid repeated power-cycling when errors continue.

Check Recycle Bin where applicable, cloud sync, File History, and other backups. A drive that shows zero bytes or drops offline may be a hardware problem, not simply deleted files.

Before You Scan

Stop moving or copying files to the external SSD. Note whether the problem was accidental deletion, formatting, or a connection fault; each calls for a different scan.

Prepare another physical device for recovered data. Never choose a second partition on the same external SSD as the destination.

Qiling Deep Data Recovery can scan an accessible Windows drive for files that are no longer visible. The steps below use the mode that fits this case; scan results are possibilities, not a guarantee of intact recovery.

Step 1. Secure Existing Copies

Check backups and cloud versions first. Only scan if the SSD stays connected and Windows identifies its normal capacity.

Step 2. Choose the Loss-Specific Mode

For deleted files choose Fast Scan; for a formatted volume choose Format Scan. Use Disk Scan when file-system records are damaged but the disk remains readable.

Step 3. Identify the External SSD

Select the external SSD by size and model or label. Ensure it is not the healthy disk you prepared for recovery output.

Step 4. Preview Small Samples

Filter by file type and preview a few high-priority files. If results are blank or corrupted, TRIM or overwritten blocks may have made them unavailable.

Step 5. Recover to Another Device

Click Recover for usable results and save them to a separate disk. Open copies before further writes or repair attempts.

Recognize the Limits of SSD Recovery

Repeated Deep Scan passes do not reverse TRIM. If the device is physically unstable or contains critical data, pause and seek specialist advice.

For future protection, keep versioned backups. An external SSD is fast storage, but it is not itself a backup when it holds the only copy.

Frequently Asked Questions

Does Deep Scan reverse TRIM on an SSD?

No. If blocks were discarded, scanning cannot recreate their original contents.

Can I use another partition on the same SSD as output?

No. Choose another physical device.

Is a loose USB cable a data-loss problem?

It may only interrupt access. Test a reliable connection before assuming files were deleted.
