I'm still strugling to format my brand new WD Caviar Green 3Tb WD30EZRSDTL SATA. Last try was on a friend's PC running Vista 64, and both the BIOS (non UEFI) and the Disk Manager see only 764Gb. I haven't used the provided PCI express card, as I've understood that it is necessary only when you want to make the hdd bootable.
I want just to format the hdd on NTFS with one partition.
Any idea what should I try?

The BIOS and Vista see only 764Gb.
How should I convert to GPT?
I've understood that the PCI card is used only if you want to make the disk bootable and only on W7 or Vista 64bit. Otherwise, if you want to use the disk as secondary drive under W7 or Vista it should work without the PCI card. There is still an issue with some Intel chipsets which might need a driver to cope with 3Tb.
Please advice on the GPt issue, how could I force Vista to format it with GPT instead of MBR? And, as the BIOS sees it on 764Gb how could I expect Vista to see more?

did you even bother to read my post (sorry)
If that not work you need to use the supplied pci-e SATA card as your BIOS in your system is not compatible with HDDs bigger then 2TB (bios update mite support it) thats why they are supplying the card due to motherboard not been compatible (any BIOS older the 3-6 months or none UEFI BIOS have an very good chance of not working )
the pci-e card is not bootable as far as I know its just an 2 port SATA card that supports 3tb disks, thats why it comes with the hdd (it also states that i think with the info that comes with it)
you can not boot an GPT disk on an None UEFI bios full stop not matter what card you use (not with out messing a lot and can make problems)

Here is an interesting link.
I'll use the pci card, as there is no other option left. In general, I read all the posts, don't worry. thanks for the advice

Here is an update.
- If the PCI card is used to format the 3TB drive then this card should be always used to see the hard drive. Therefore you cannot move the drive to another computer without the PCI card.
- My drive has been formated by a jukebox at 2.1Tb and in fact the jukebox created a partition of 2.1Tb and another of 764Gb. The 2.1TB partition is visible/accesible from W7/Vista without the PCI card.
- In order to format the drive and to use it afterwards without the PCI card you need a new W7 PC with a UEFI BIOS. Aparently only few motherboards, new from 2011, have UEFI BIOS inside.
I've given the drive to a computer shop to format it NTFS using a motherboard with UEFI BIOS. They told me that it will take 30-40 hours and then a WD software to aligh heads and sectors needs to be run.
