Frequently Asked Questions

Encryption changes the order of operations: Windows must first unlock the BitLocker volume. A scan cannot bypass the password or recovery key, and formatting would not recover the encrypted contents.

Confirm the Drive Can Be Unlocked

Use Windows' BitLocker prompt and the authorized password or recovery key. If the key is missing, check your legitimate key backup or administrator before trying file recovery.

Once unlocked, verify that the drive appears at its expected size and that any visible files can be copied. A USB device that disconnects repeatedly may need specialist handling.

Before You Scan

Do not format or initialize a locked drive. Unlocking it is not the same as deleting data; avoid unnecessary writes after access is restored.

Prepare another physical disk for restored files. Note whether the missing data was deleted after unlock, or the entire unlocked volume became unreadable.

Scan an Unlocked BitLocker Volume

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. Unlock and Copy Visible Files

Unlock the drive in Windows using a valid key, then copy any readable files to a separate disk. Do not continue if the drive vanishes or shows hardware errors.

Step 2. Choose the Loss Mode

For recently deleted files choose Fast Scan or USB/SD Scan for the removable device. If the unlocked file system is damaged but readable, Disk Scan may be more relevant.

Step 3. Select the Unlocked Volume

Choose the correct USB drive by capacity and label. If only encrypted raw sectors are visible, stop; the volume must be accessible after unlock.

Step 4. Review Candidate Files

Filter by file type and preview files where available. Check that results are readable content rather than encrypted or damaged fragments.

Step 5. Recover to a Separate Drive

Click Recover for validated candidates and save to another physical disk. Verify the copies before making changes to the BitLocker device.

Keep the Recovery Key and Copies Safe

Store the recovery key in an authorized secure location, separate from the USB drive. File recovery software cannot recreate or bypass a lost BitLocker key.

If the unlocked volume shows persistent read errors, stop repeated scans. Consider professional imaging that preserves the encrypted device's state.

Frequently Asked Questions

Can recovery software bypass a lost BitLocker key?

No. You need an authorized password or recovery key to access encrypted contents.

Should I turn off encryption before scanning?

Not necessarily. First unlock and copy accessible files; decrypting the entire device creates additional writes and risk.

Can I scan the drive while it is still locked?

A normal file-recovery scan cannot interpret locked encrypted data as files.
