G-RAID from Mac to PC

I’m having trouble finding the best way to get my G-RAID drive, previously working on a Mac, to work on my Dell PC without completely reformatting the HD. The PC recognizes the drive but due to formatting (I’m assuming) it’s unusable. Is there a way to get it to work with the PC without formatting and losing all of my photos? Is there a way to use it on both PC and a mac at the same time? If I need to go back to the mac and back everything up first, where in the world am I going to store 2 TB of photos in the interim lol

Thank you

if you don’t want to format the G-Raid for Windows, you can install Paragon HFS+ for windows on the Windows machine.
