Hello is there a way to copy the saved data from an external hard drive to my laptop/computer?

We really just want to retrieve all the saved game data off of an old 2-TB hard drive that no longer works in the PS4.


Background: Before PlayStation allowed external hard drives by USB, I swapped out the original for a 2-TB for my sons. When my son did the recent update to 4.73, the hard drive stopped working so I replaced it with the original hard drive. However all of their saved game progress was on the 2 -TB hard drive. Is there a way that I can back-up /copy the 2 TB saved data to my laptop for "save keeping" (hopefully to transfer to a new external hard drive or flash drive that is not corrupt that they can attach to the PS4 via USB).

Note: I'm not a techie or a gamer. I am just a mom trying to help my kids get back to "happy" and I'm not willing to pay the $100 that PlayStation quoted me for a refurbished hard drive.
