I could be completely off mark here, but does that external drive have eSata too ? Your problem resembles a lot something I struggled with a while ago. I'd bought an external hd case + a 3TB drive for my girlfriend , the external hd case supported eSATA and usb . I had a lot of problems when connecting that 3TB drive to my laptop via usb (I didn't have eSATA), the drive showed up as only 2TB . It turned out that the external drive case required to be connected via eSATA for +2TB drives, the manual said so, I had only forgotten about that . Via eSATA the drive was recognized as 3TB, I think the 'problem' was OS agnostic, since the same happened on my girlfriends mac. regards Joar Jegleim On 14 February 2013 12:16, Scott Bennett <bennett@cs.niu.edu> wrote: > I recently bought a 3 TB external hard drive.
