"....and i had to change the settings through Disk Utility on my mac to be able to transfer files from my mac to my HDD"

What do you mean by that? Did you format?

If you reformatted the drive to MacOS it won't work on anything but a Mac.

What did you do?

Assuming that you formatted the disk: you have to do a new format with DiskUtility and use format Exfat.

Copy all files that are only on this disk to another disk, because all data will be erased.
