I have vista 64 sp1 installed on a RAID 0 2*74GB raptor drives and I am trying to set up my 2*250GB WD caviar drives in a second RAID 0 array, but when I enable the second array, Vista will no longer boot. I have Asus P5N-T deluxe mobo. I created the 2nd array in the RAID bios and have left the original array with vista checked as the boot drive. I have also ensured that these 2*250 are enabled for RAID in bios. Any suggestions as to why this is causing vista to not boot? (note that one of the 250 gb drives is currently partioned, would this impact it?)

Yes, having the old partition on there can cause that problem. With the partition defined, Vista is expecting to be able to read the file system structures on the new RAID array, but now that the drive is part of a RAID, part of what Vista is reading is coming from the other drive, which is blank, so there are multiple pieces of the file system structure that Vista thinks is missing.
You need to erase both drives individually before putting them in the RAID. Try Active@ KillDisk ... free for single-pass erasing, and has both DOS and Windows versions. You don't need to erase both drives fully -- just let KillDisk run to about 3-4% on both drives to erase the first few thousand sectors. This will get rid of the MBR, partition table, & other structures enough so that Vista will think the drives are blank.
After that, put the drives back in the new RAID 0 and you should be good.

Hi, thanks for your answer. I deleted the partitions and reformatted in NTSC so both 250GB drives were empty but formatted (with no partitions). I then went to BIOS and enabled RAID on those drives and set up the stripe RAID array in the RAID menu. Again, when I restarted, Vista failed to load and I was taken to my Vista start up disk (CDROM is secondary boot priority to HDD). The only way to get vista to load was to go back and disable the RAID. This would not lead directly to vista loading on the next restart however. It would only load the vista setup disk again and I had to do a start up repair and then reboot in order to go back to vista.
I think you need to go into the bios and ensure that the desired RAID array is higher in the boot order than the undesired array. ...or to make it simpler, just make sure the desired array is first in the boot order.
