Creating >2TB in Vista Ultimate x64
Posted on 2009-04-08
I'm tyring to create a RAID5 array to create a 4.5TB array
Here's my setup:
Vista Ultimate x64
Asus A8V Deluxe mb
Athlon X2 4400+
4 x 1.5TB Seagate hd on RAID5 (using HighPoint 1740 RAID card)
What I want to do is create a boot partition (500GB) and another partition (with the rest of the available space) for data.:
The array creation went fine, 4.5TB (4.5T bits => around 4T bytes) RAID5 array was created. When installing Vista, I created the boot partition and after that, the remaining space became 1.5TB, which indicated a BASIC disk was created, which has a limitation of 2TB partition.
After the Vista installation was done, I saw 3 partition on the disk:
- 500GB Boot partition
- 1.5TB unallocated space
- 2TB unallocated space
and I was unable to create the 4TB second partition for Data drive, or to convert the disk into GPT or Dynamic Disk (I guess they can't convert disk that contains the OS).
The question is, how can I create the 2 partition I wanted (500gb and 4TB) under Vista x64? I was thinking about using another drive to install Vista temporarily to convert the array into GPT, remove the temp drive, then re-install the OS in the now-GPT disk. But I read that you cannot boot from a GPT drive.
Any help would be appreciated.
