Dell XPS 435T - Largest Harddrive Supported - Windows 7 Ultimate 64 - Bit

I believe this article will answer most of your questions:  WD's Caviar Green 3TB HD.  It appears that the computer should handle a 3 TB drive as secondary, but requires either a UFEI BIOS or a special card to be used as a boot drive with all 3 TB accessible.

EDIT:  I don't believe this computer has the necessary UFEI, but I could be in error.

Thanks thus confirms what Western Digital, Seagate and Hitachai are posting on their websites. The 3TB drievs will not be the boot drive.

They call it 3 Terabyte cuz its Terribly small.

:P

I've been getting Western Digital Drives over Seagate because I recently purchased 2TB Seagate Drives that go click click click click about every minute or so.

Never had this issue before. Seagate said they knew of the issue and a firmware patch would fix it.

HOWEVER firmware did not help in this case.

No Way I trust my data to a drive that wants to beat the heads to death.

Just wanted to get this on record to help other people. It took me several hours to get the WD 3 TB working. I have Windows 7. The computer is a couple years old. Most importantly, the SATA controller is Intel AHCI. The bios does not recognize the full size of this (3 TB) HD. Neither did Windows 7 (saw it as less than 800 GB). After a few different approaches, I installed the latest Intel Rapid Storage Technology. The F6 method was not required. After a restart, Windows saw the full disk size. Note I am not using this HD for booting (I suspect that would require a bios change).

3TB Booting Requires 64 bit Bios and OS with GPT partitions.

UEFI processor mode can be either 32-bit (x86-32, ARM) or 64-bit (x86-64 and Itanium).

Its a Thumbs Down to MSDOS.  MBR is 2TB PERIOD END.

... on a UEFI-enabled system.
