Windows 7: Getting my 4TB to be recognized on XP

Getting my 4TB to be recognized on XP

I just got a new 4TB drive
My Book Studio Edition II 4 TB

Now apparently Windows XP can only recognize drives upto 2TB so a single 4TB drive isn't recognizable.

Now while I use Windows 7 at home, my school computers all use XP.
So I need to find a way to get these computers to recognize the drive.

I tried making two seperate partition using Dsk Manger (1.90 TB each) and still it didn't get recognized.

Is there any way to solve this problem without losing the ability to use the drive to its fullest?

Correction - that document refers to NT4.0. You need to have a cluster size of 2048 byte (8,796,093,020,160 (8TB)) for Windows 7.

I'm not aware of any way past this limitation. It's listed right in the spec sheet that this drive will only work on Windows Vista and up.

wow 4 TB. I wonder what average consumers do with so much disk space.

Cluster sizes need to be less that 32k for TB+ drives to be recognized. Bear in mind that 7.8 TB is the limit for NT.
So would this make it so the drive could be recognized?
How do I do this. I'm using NTFS

Was the drive partitioned/formatted under XP? If so, it should have allocated 32k blocks already and be available to both OS'. Otherwise, Windows 7 may have formatted using 64k blocks, in which case you will need to reformat/recreate the partitions.

Backups - lots of backups .

Apologies, I had a pretty bad typo in my earlier post, it should be 7.8GB - not 7.8TB.

Big difference.

As I mention, use a cluster size of 2048 bytes (8,796,093,020,160 (8TB)).

Do you guys really keep so many backups of data? I'm all about backups. My server has 2 drivers that are synchronized to each other every 2 hours with robocopy. In addition, I run a robocopy job to 2 external hard drives on a regular basis and 1 drive stays at home, while the other one stays in my office. I certainly wouldn't advise storing all of these backups on one physical device like this either. It's far better to have the data in multiple places in case of fire, or theft.

I have two disk drive sets, call them System and Data.

The System drive set is 4x 1.5TB on the on-board ICH10R controller, and has a 300GB RAID 0 array with two 100GB system and one 100GB app temp partitions, and a 2.7TB RAID 10 array all used for data image backup.

The Data drive set is 6x 500GB on an Areca ARC-1220 PCI-E controller, and has a 100GB RAID 0 array for sys Temp & pagefile, and a 1400GB RAID 10 array with a 780GB Data partition and 570GB Sys Backup & Stuff partitons.

So each drive set provides fault-tolerant backup image storage for the other.

From the Data and System image backup areas I copy to a single harddrive (currently 750GB or 1TB) on a hot-swapable bay for external backup using a script that also copies real-time versions of special dynamic files, such as mail.

I use Paragon Drive Backup Pro to create the backup images. Creating a System image (~25GB) takes about 2.5 minutes. Creating a Data image (~500GB) takes about 55 minutes. Copying to the external storage drive on the on-board Marvell controller takes about 2 hours, but is not too intrusive as the images are static.
