3 TB disk troubles

[Joar Jegleim]

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.
