2TB Iomega HDD Cannot be Erased

Hi, I'm using a Macbook 1,83Ghz Intel Core 2Duo with OS 10.5.7. Just got a new Iomega 2TB external HDD which I intended to use just for back up of vídeo files of my Scratch disk for Final Cut which is an external FW drive. I cannot format the Iomega drive in Maco OS Extended (Journaled). Only in MS-DOS(FAT). If I try Os (Journaled) is gives the message "Disk Erase Failed with the error: File Sytem formatter failed". Now if I try to partition the drive, I can only do it using 4 partitions which renders 465GB each. They are in Mac OS (Journaled) but if I choose the drive and not the volumes, it says it is in MS-DOS(FAT)! Can the drive be in FAT and the volumes in OS (Journaled)? Even so, I would like to have the entrie HDD as just one partition in Mac OS(Journaled) as many of the files I'm putting there are 13GB (captured miniDV tapes). Any ideas why I cannot do this?

Thanks.

TRy again but use this method

Select the disk and then the Partition tab

Select one partition with the Mac OS (Journaled) format

In the options button select GUID partition table

Apparently this is an issue with Disk utility sometimes using the wrong partition map when formatting drives

Or I think many discs actually comes with Master Boot Record preselected so you can make DOS/Windows start-up discs and Disc Utility does not change it until you tell it to do so. It does work with Master Boot Record if the partitions are not too big.

Thank you both for replying. Selectign the GUID table solved the problem.
