Raid 5 Array Initialization?

Hi,

So I'm building a new system, and I am trying to install Windows 7 Professional 64-bit on a RAID 5 array of 5 Raid-class F3R 1TB Spinpoint drives. I'm using my MSI Motherboard's Intel Rapid Storage Technology utility to configure my RAID array. So when I configure it with all five drives, the Intel RST manager displays the array status as "Initialize", whereas if I leave a drive free and only configure the array with 4 drives, the status is displayed as "Normal".

Intel has explained this here (http://www.intel.com/support/chipsets/imsm/sb/CS-029124...), but when I go to the part of the Windows 7 installation screen where you choose which drive to install the OS on, it gives an error saying "windows cannot be installed to this disk. the computer's hardware may not support booting to this disk. ensure that the disk's constroller is enabled in the computer's bios menu" when I have all five drives in an array.

Is there any way I can configure it so that I can put all five drives in the array? Or will I have to leave one drive out to install the OS on, then put the other four in RAID?

Thanks for the help!

You can not install a Win7 into a HDD greater then 2TB - Your RAID5 is a 4TB volume
Let assume you can by partition it as 2TB, then you won't able the see the remain space

Here is what I recommend, after you built you system will complete boot within 10sec and a massive storage transfer at 230BM/sec

1_ Get a SSD 64GB (W/R over 175MB

Install OS in this drives - Note: In MB's BIOS change the SATA mode to Enhance, 32bits transfer = Enable

2_ Create a 64MB/128MB RAM Disk to catch Internet content:
Get a free software here:
32bit - http://www.datoptic.com/Download/VistaRAMDisk.zip
64bit - http://www.datoptic.com/Download/VistaRAMDisk64.zip

When install, you need to right click an run as Admin, in order to install.
Change the IE, FireFox, Chrome... all the web browser to this cache drive

3_ Use this hardware raid to create your raid5
Fancy controller: SPM394 - Hardware raid 1 to 5

Fast, simple controller SPM393 - five drive hardware raid. Mount this to a http://www.datoptic.com/pci-to-scsi-1-bracket-adapter.h...

You may move your temp files this raid5

That is basic all of it... Guarantee your system can have 30~40 windows at the same time with no problem of slow down or sluggish

Once you are happy with the set up:

Use this Clonezilla Live 1.2.8-23 - http://distrowatch.com/?newsid=06602
Create a C: disc image to your RAID5 drive....
If anything just restore it... you are back in business in minute.

You can still create 2 partitions, using all the space on the drives and installing windows on one of them.

The issue is that a single disk volume > 2TB requires the use of a GUID partition table. The conventional MBR partition table maxes out at 2TB.

Windows 7 can boot from a GUID partition table as long as the motherboard supports it - the problem is that most motherboards don't have the EFI (Extensible Firmware Interface) BIOS required to do this.

Partitioning doesn't solve the problem - you still need to use GUID partitions on a volume that large and even if you create a small GUID partition you'll still have the same motherboard boot issues.

What you CAN do with some RAID controllers is to create multiple RAID volumes from a single pool of physical disks. If the RAID volumes are less than 2TB then you can avoid the problems with booting. You could create one RAID volume of, say, 100GB to store an MBR-formatted OS partition for booting, with the remainder set up as a large volume using a GUID-formatted partition for data. (GUID data partitions are not an issue since you don't have to boot from them).
