D: is only a drive letter. It may identify another partition on the same physical disk, a second internal disk, or an external device, and that distinction matters when choosing where to install and save recovered files.
Open Disk Management and match D: to its disk number, size, and file system. Do not assume D: is physically separate from C:; the two letters can share one device.
Check whether the missing files were deleted, hidden, or moved to another folder. Recycle Bin, File History, and cloud backups may have a complete copy.
Stop new writes to the physical disk holding D:. If C: is another partition on the same disk, installing recovery software on C: can still reduce recovery chances.
Prepare an output drive on a different physical device. Record the deleted folder and file types so you can filter results rather than recovering everything indiscriminately.
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.
Identify D: by capacity and disk number, then inspect Recycle Bin and backups. Connect a separate destination before beginning recovery.
For a recent deletion choose Fast Scan; choose Recycle Bin Scan if the bin was emptied. If D: is actually a removable drive, USB/SD Scan may be appropriate.
Select the original D: volume in the location view. If its letter changed, rely on disk size and label rather than scanning whichever device currently happens to be D:.
Filter by file type or path and preview representative files. A result from another partition may have a similar name but not be the missing version.
Select candidates, click Recover, and save to the external output disk. Check files open before normal use of the source resumes.
A different drive letter is not enough: C: and D: can reside on the same physical disk. During recovery, choose another device for both installation and output when possible.
If D: disappears or shows read errors, stop routine writes and address the disk's condition before repeated scans.
Only if C: is on a different physical disk. Check Disk Management first.
Match the disk by size and label; letters can change after reconnecting storage.
It may for local volumes, but not every removable or network location behaves the same way. Check before scanning.
