Does the Smartware "Retrieve" function modify the data on the source drive?

I have a WD My Passport with a Smartware backup of my account files. I had to reset (reinstall) Windows 10, and tried to restore the mail files stored on the My Passport. The first time I retrieved the data the files were there, but I accidentally removed them from my computer (C: drive was full). When I ran retrieve again, the directory was no longer on the My Passport. Is there any way to look for deleted files on the My Passport?

Hi,

No it should not modify the source. Try to go manually through the drive into the “Smartware swstor” folder and check if you can find your files there.
