Can I recover files from unallocated space?

“Recently, I plan to copy some files from the Seagate external hard drive to my computer with Windows installed. But I can’t see it in Explorer. I open Disk Management to check out the status of it but find that it shows as unallocated space and the connected SD card has one partition allocated. I realize that I have removed the partition on the external hard drive somehow, although what I want to clean is the SD card.

There are lots of files on the Seagate drive and I don’t want to lose them. How to recover files and data from the unallocated space after partition deletion? I’m looking forward to your advice.”
