    Hello,

    I'm trying to format a WD Caviar Green hard disk in a Sata caddy but I'm having trouble with disk utility.

    It seems to only want to format it as 850GB instead of 3TB.

    I've seen a few threads in other forums but they were all windows based and too technical for me.

    My caddy does support 3TB.

    Thanks for any help, regards, Daniel

    Caddy? What caddy? What computer? What SATA card? In Terminal type:

    Code:
    diskutil list
    reply back with the result, ideally with code tags (highlight text, click the # button in the toolbar).
