I have setup a Asus P4C800-E Deluxe MBO using it's Promise 378 Controller for RAID 0+1 configuration.
The hard drives are 2 Western Digital SATA 120GB and 2 IDE 120 GB drives (1 Western Digital and 1 Seagate) All are 7,200rpm.
After setting up the BIOS and then using the Promise Utility the Array 1 looks odd.
Array 1 = 1 WD drive is set as STRIPE, but the second shows FREE.
If I setup the Array with both as Yes the Array shows 240GB. It should be 128GB according to a previous installation.
Not only that, but the IDE drives are not seen in the hard drive list in the utility. (They are seen when the OS is loaded as drives E & F) in WInXP Pro.
How do I configure the Array and how do I get the IDE Drives to be seen in the Array selection area?
I beleive the SATA drives are set correctly. The IDE drives are set as 1 primary and one slave.

are you sure you can mix SATA and IDE drives?

you might be able to setup SATA array or IDE array, not sure about mix and match. better double check the manual.

That is not the information I am, looking for that is worth 500 points.
I need someone who understands the Promise Controller and Array setup.
Right now the array only gives me the choice of Stripe or Mirror. If I choose the two SATA drivers I get 2+0 RAID, not the 0+1 I want.
The OS reload ended up on one of the IDE drives and did not install on a Array 1 drive (SATA).
Anyone needing more detail, please ask.

Ok, Ok I re-read the manual and discovered a big Opps.
The IDE cable was connected to the IDE cable conntection of the Asus Motherboard.
Guess what! There is a PCI-IDE connection that the IDE drives connected instead of the standard IDE connector.
Now the drives are all seen in the Promise Utility.
Now to figure out how to Fdisk the drives.
I have a USB external HDD of 120GB that is use to hold the Image needed to regain my original system back to the way I want it.
However now in the BIOS no HDD drives are seen and the manual states to formate the drives in Fdisk.
The OS install CD for WinXP Pro will not show a DOS prompt to get to a Fdisk.exe.
I will try to load a WIn98 Boot disk and get to Fdisk, but I think there are problems with NTFS drives and Fdisk?

You don't need to fdisk it, to install XP on the RAID array just boot up with the windows CD then press F6 to load the Promise driver at the beginning. Once that's done you can install XP on the Array.

By "image" i take it you have a ghost image? depeneding on how it was ghosted you restore it by booting up with a ghost bootdisk and restore "Disk or Partition from Image".

Here is where I am at:
Created new Array using my 4 drives (2 SATA and 2 IDE all 120GB)
Restored Image from Acronis "True Image" that was created prior to this array and rebuilding issues.
Loaded my OS (WinXP Pro) on Array and then replaced it with the image.
The Array choices did not look right. Before when I had three drives (two were in RAID 0 configuration) and third used for backups showed the RAID 0 array with 128GB Stripe.
In the current setup I saw the size of the Array as 228GB (or there abouts) which told me it was too large. I down sized the setting to what each drive was set before this Array (114GB).
The Array 1 now shows 2x2 Mirror/Stripe with all drives assigned to the Array and at 111.790 GB and UMDA Mode 2 (for two drives) and UMDA 5 for the other two.
Does this sound like the array is setup correctly?

One other observation: The "Disk Management" reading for the "C" drive shows "111.78GB Healthy and 111.73 Unallocated.
Does this mean that the formatting was done incorrectly and the array need to be rebuilt?

If you have 4 drives and you are doing RAID 10 then your RAID array should be around the 228GB you posted. Looks like you created a partition of half the size (111.78GB) of the Array so you should be able to create another Partition and you'll have a drive D of 111.73GB. If you want the whole 228GB in one drive (C in your case) you'll have to reinstall windows.

OK, I will reset the drives and reinstall the OS.
You're saying the 228GB is correct and the 2x2 is correct.
If so I will close out this issue after completion.
Thanks
