So I have a second 1tb WD Black hard drive where I store all my games and files but I can no longer move anything into the hard-drive even tho windows says I have 500gb of free space. I reformatted but I still have these problems. Should I RMA it? Or should I convert it from FAT32 to NTFS? (Last resort as I also dual boot with OSX and use that to transfer files across from each other)
