    Do the following:

    Extended Hard Drive Preparation

    1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)

    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.

    3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the volume(s) mount on the Desktop.

    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.

    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.

    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

    Sorry for post jumping but what's the largest size of drive available for the mac?? I thought it was only 1Tb drives

    I'm not wanting to fill my machine with drives just to replace them further down the line with larger drives unless I need to

    a 2Tb internal drive would be a godsend right now for time machine and network storage

    Hi,

    right now 1.5TB is the largest avaiable and wthey work with Macs.

    For 2TB give it a little time

    Take care

    Cool might just get the 1.5Tb for now as a file storage and then when the 2Tb comes out I'll use that to back everything up
