I just bought a Samsung G3 Station External Hard Drive (1TB) and I'm on a Mac. I plugged in everything and I can't seem to transfer my files to the EHD. In the EHD, the Basic Information document says that "If the drive has been formatted to NTFS, data stored in the drive can only be read by Mac systems. Reformatting for Mac OS may be required." I followed the steps to reformat Mac OS and when I was reformatting, a prompt came out saying "Disk Erase failed. Disk Erase failed with the error: Could not unmount disk". Can someone help me out there?
