2 Tb Wd Elements Drive Not Recognized By Mac Os X Yosemite

Hi,

I recently purchased a 2 TB WD Elements external hard drive for back up purposes.
I was able to back up the information, but I just got a new replacement mac and this new
mac doesn’t recognize the drive at all. SO, I have two external 2 TB WD Elements drives that
my MAC doesn’t recognize formatted NTFS. I tried Tuxera NTFS and there was no change.
