Raid 0 volume shows incorrect GB size in C: drive

[Guest]

P4 550 3.4 GHZ

Intel D915PBL mobo

Intel 82801FR SATA raid controller (on board)

Corsair memory 2 x 512mb in dual channel

2 x Western Digital 200GB SATA HDD totalling 400GB

Windows XP MCE 2005 O/S SP2


I have installed many operating systems but never a raid array.

I thought the install went smooth and I configured the raid 0 using the
Intel utility in windows. That seemed to go well. Prior to configuring the
raid the computer displayed a C: and a D: drive of about 187GB each.

Afterward it was one C: drive of about 186GB.

The raid utility shows that it is a RAID 0 setup utilizing the 2 drives and
it displays the total capacity of 372GB.

What did I do wrong?

Shouldn't the C: drive show the same total as the raid utility?

When you build the RAID0, I don't think it just adds the 2 existing
partitions, rather takes the 1st (C and stripes it across the 2 disks.
That means that you now have C: at 186GB and a like amount unused.. Check in
diskmanager (Start->Run diskmgmt.msc
