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

I purchased this computer in 04/2009 and woulld like to add a couple of 3TB drives to the system to replace an existing 1TB and 2TB drive. The boot drive is a 10,000 RPM Western Digital and the 1TB is drive D and 2TB is drive E.

 

The system has the mopst recent BIOS and WIN7 has been upadted to SP1.

 

I am looking for verification the the system will fully support the 3TB drives.

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.

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.

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

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.
