RAID 5 array not recognized in XP

I just installed Three 300GB Seagate drives and connected them to an LSI Megaraid -150-6 PCI sata raid card. The dos bios utility sees all teh drives and i initialized the drives into a 900GB RAID 5 array, which gives me 600GB storage.

However, in XP when i boot it up, there is not drive shown that reflects my raid array. I have the card's drivers instaled and the card is listed in Device Manager. I installed LSI's XP utility and it sees the array and individuals drives.

the documentation is horrible and being new to all of this I have no idea what is wrong. i expected that after initializing the array in the bios utility and installing the XP driver for the card, i would just see the raid array as another drive letter wrth 600GB free space.

What am I missing?
 
This may be a pretty simple solution. I believe that those drives still need to be formated for use in Windows. So if you go to your Computer Management, there should be an option there to format those drives.

Control Panel\Administrative Tools\Computer Management

Once there choose Disk Management. The drives should be there, just need to be formatted. Hope this helps and good luck!!! I just recently setup some SQL servers at work with Raid 5 and this was the issue as well.

I LOVE YOU. This was it! Thanks so much for the tip.. I have no idea why there is nothing in the documentation that mentions this.

Btw, shoudl I be creating a primary or extended partition on this thing? The useful MSFT help info wasn't that helpful 🙂
 
If you are going to have more then 4 partitions on the drive then you need an extended partition. But if you are going to have 4 or less, then primary partitions will be fine.
 
Primary would be what you want unless you plan to have a fair amount of partitions. MCrusty is correct. Glad to be of help.
