    You couldn't get this to work, even with the red dip switch in the enclosure?  I fixed 3 of my OWC enclosures in this way.

    There are no dip switches anywhere on or in my LaCie or the NexStar cases.  It's likely I'll get an OWC case to put the 3TB drive to good use.

    Ah gotcha.  Yes, in that case, I imagine that it's an issue with the chipset or something as you said.  Sad that those enclosures can't be put to good use with modern drives, but I guess you can keep them around for your smaller (older) drives.

    Via USB on MacBook Pro (below) does not mount and shows as ~800Gb in Disk Utilities

    on MacPro Desktop  running 10.6.8 it works fine.

    OS X Lion 10.7.3 (11D50)

    2.33 GHz Core 2 Duo

    I'm having the same problem. Have two 3TB WD drives.  Using an KingWin EZDock2 which supposedly supports up to 3TB, with MacPro 10.6.8 and drive shows up as 800GB.   Tried it in the LapTop running Mavericks and same thing.   Also, tried with an Apricorn DriveWire on the Laptop...still sees the drives as 800GB.

     

    Any help would be greatly appreciated. 

     

     

    Thanks.

    3 TB showing as 800 GB is the classic symtom of something not understanding the new Advanced Format of drives.

     

    Was it formatted on an older Mac or older Case beforehand?

    It wasn't formatted before hand and was a 3TB Western Digital Desktop Drive.   I was using it in an KingWin EZdock 2 adapter (USB 2).   After reading this thread I went to Fry's and bought a USB 3.0 Dock Adapter (Vantec NextStar usb 3.0 hard drive dock) and Voila.  It sees all three TB.

    Thanks, seems the WZdock2 chipset did not understand Advanced Format's 4096 Byte sectors.

    You need another enclosure that handles Advanced Format & big drives.
