Raid 0 volume displayed on C: drive is half the GB total

[Guest]

P4 550 3.4 GHZ

Intel D915PBL mobo

Intel 82801FR SATA raid controller (on board)

Corsair memory 2 x 512mb dual channel

2 x Western Digital 200GB SATA HDD totalling 400GB

Windows MCE 2005 O/S with 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, "my 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 their total capacity as 372 GB.

What did I do wrong? Shouldn't the C: drive show the total as does the raid
utility?

It sounds like you have set up RAID 1 or when installing Windows it did not
recognize the RAID setup and only used one drive. Run diskmgmt.msc and see
how many drives Windows thinks you have. Why do you want to use RAID 0? The
speed increase will be minimal to not noticeable and you are doubling your
chances of losing all your data to a drive failure.

You need to create your raid before you install windows if you want to use full capacity of both
drives, there should be a hot key sequence at boot to create the raid and then do the install of
windows. This is how I have always done raid setups.
