I have paragon windows ntfs on my mac, & wanted to format an external hard drive to ntfs. i did it through disk utility, windows nt system was among the options. I did an erase & writing zeros to the hard drive 1st, then did a format. when I looked at it in disk utility, there are 2 icons for each drive, & for this drive, one was the factory name or 1TB PI-367, formatted mac os journedled, & then below it is another drive icon for the same drive; movies, (what I named it) formatted windows nt. i named the drive movies for storing backups of my dvd collections. did I format it to ntfs? i am a little confused as in how disk utility is showing the drive.
