Thanks — that symptom makes the problem clear: 4DDiG is linking the source and target checkboxes because the UI is showing the same physical disk (Seagate) on both sides and the program is trying to be helpful / prevent invalid restores — but it’s picking H: (a partition on the same Seagate) as a target when you tick D:. We must force it to use the 128 GB flash as the target (a different physical disk).
Try these short, safe actions in this order and tell me what happens (or paste the PowerShell output I ask for if you get stuck).
Quick attempt A — select target first, then source
- In 4DDiG Restore window, pick the imported backup from the dropdown.
- On the RIGHT pane expand the physical disk that is the 128 GB flash (it will show the friendly name like “General USB Flash Disk, MBR” and the partition under it). Click the checkbox for that USB partition first. Do NOT touch any Seagate boxes.
- Now on the LEFT pane tick the checkbox for D: (the source).
- The center should show the left→right mapping. If it does, click Restore (after confirming “fit to target” and sector‑by‑sector off).
If step A fails because ticking D: always forces H: to be checked:
- Immediately after the auto‑check happens, manually uncheck H: (on the right) and make sure only the USB partition remains checked. Then proceed to Restore.
If you can’t uncheck H: or the UI keeps forcing it back, do Quick attempt B.
Quick attempt B — temporarily remove ambiguity by unplugging the Seagate’s other partitions
- Safest: close 4DDiG.
- In Windows Explorer safely eject the Seagate (Safely Remove). Physically unplug the Seagate USB.
- Leave only the 128 GB USB plugged in + your PC (so 4DDiG can’t auto‑select any partitions on the Seagate). Reopen 4DDiG (Run as Administrator) and import the image file again (or make sure it’s still in the dropdown).
- Plug the Seagate back in. Now in the Restore dialog 4DDiG should still show the imported image — select the image, then the right‑pane should clearly show the 128GB USB as a distinct disk (tick it) and the left pane should show the D: recovery partition on the Seagate (tick it). Proceed.
This unplug/plug sequence often prevents the UI from auto‑linking partitions.
If unplugging the Seagate is not convenient, try Quick attempt C.
Quick attempt C — confirm which drive is which and paste outputs (I’ll point exact boxes)
Open PowerShell as Administrator and run these two commands and paste the outputs here (copy the whole block that prints):
Get-Disk | Format-Table Number,FriendlyName,BusType,PartitionStyle,Size,IsRemovable -Auto
Get-Volume | Format-Table DriveLetter,FileSystem,Size,SizeRemaining,FriendlyName -Auto
I’ll read the output and tell you exactly which checkbox to tick on left and right (I’ll identify the source and the 128 GB target by size / FriendlyName so there’s no guesswork).
If none of the above works
- We’ll use the safe alternate: restore using Macrium Reflect or Clonezilla (I’ll walk you step‑by‑step). That avoids 4DDiG UI quirks.
Which do you want to try now?
- I’ll wait while you try A (select target first) and B (unplug trick). If you hit the auto‑check again, paste the PowerShell outputs above and I’ll give the precise checkboxes to use.
