Partition or Volume - Create New

Hi Sean. I was hoping to find the answer to my problem here but no go.

I bought a new 3TB drive to put into a raid cabinet with a 1TB drive, hoping to make up 4gb jobd but found out that I can't and have to use it non-raid as 3+1.

But while the 1tb works fine, the 3TB only allowed me to use 2TB and the rest unallocated. I can neither render the unallocated space into a partition I can then shrink, nor will windows allow me to extend the 2TB section.

Screen shot included.

Many thanks, Brink. I just read in the Mediasonic RAID cabinet instructions: "Note: For 3TB Hard drive, users must format in GPT Partitions and use Windows Vista or Windows 7 in 64bit."

I can't believe I missed this.

But is it OK (I don't know much about this) to keep the other drive in the RAID cabinet as an MBR disk or will it cause a conflict?

Much appreciated. But just one more question. I can't combine the two to be one huge 4gb disc, eh? The manual (for the RAID cabinet) says that JOBD writes first on one disc then the other so they'd have to be the same size and type, right?

Anyway it worked except when I rebooted strangely it was "offline." I just restarted and everything was ok again. Picky things, these computers but I guess they're still newish.

Ah! Thanks again, Sean. They're both 7200 but here's the rub: "the smallest size HDD will cause only the same small amount to be use by the larger HDD's in the RAID"

Yup. That would certainly defeat the purpose. LOL! Thanks for your help. How do you find the time to be kind to so many strangers?

Hi, there

In your tutorial :

Using Disk Management
1. You will first need to shrink a partition or volume from the free space on a disk to create unallocated space on that disk to use to create the new partition or volume with on the same disk.
NOTE: If this is a new HDD that is all unallocated space, then you can skip this step and go straight to step 2.

I have about 130 GB in my drive C, do I go to step 2? Thanks.
