The MBR file system has a limit of 2.2TB.
To use more than 2.2TB on a single drive it is necessary to use the GPT file system when initializing the drive.

Since your PC boots and runs Windows from Disk 1 you will have no problem switching file systems. Just be certain that there is no data on the drive, as the procedure to switch will erase all of it.

TVeblen:

I thought MBR just prevented partitions larger than 2.2 and figured he should be able to make two partitions on that drive--one about 2.2 and the other for the remainder.

No? That 2.2 limitation applies to the entire drive, not just partitions?

If so, I've learned something---thanks for clarification.

That is my understanding (limitation is for the MBR system).

Tell the truth, I couldn't remember exactly, so I looked it up here:
Support for Disk Drives Beyond 2.2 TeraBytes (TB) and 4K Advanced Format Sectors

I think the confusion comes in because of the utility/driver you can run to get more recognized on legacy systems.

Yes. I think I've got it now. I'm expecting a new 3 TB drive Monday and need to know what to expect. I hope to use GPT and have 1 partition for the entire capacity. Data only, not a system drive.

The only issue is the strange windows limitation of requiring efi to boot from a gpt drive.

Bios handles gpt just fine.

Do you know if it is just 7? What about Windows 8?

Not a problem with data drives. Enjoy!
