My Situation
I'm looking for suggestions regarding getting Windows XP to boot from a RAID0 partition. I've got XP running on an 80GB PATA drive and I've got two new 350GB SATA drives.
If I Were a Witch Doctor:
In a perfect world, I would plug-in the two 350s and setup the motherboard's onboard fake-RAID to stripe the disks. Then I would boot to Windows and install the RAID drivers. Then I would boot-up in a live CD and copy the NTFS Windows partition over to the new RAID array. I would 'ntfsresize' so that the filesystem would take up the whole 700GB of the striped partition. Finally, I would unplug the 80GB and boot to Windows from the 700GB array.
Anticipating Problems:
I suspect that the above scenario would be difficult or impossible for a number of reasons. I imagine that the BIOS won't know how to load the Windows bootloader from a RAID0 partition and that the Windows bootloader wouldn't know what to do either (even if it could be loaded).
Aside: My Usual Tool Set
I know that, in Linux, I would just create a tiny boot partition in unRAIDed space. It would include the kernel and an initial root-disk that would setup the RAID device and then pivot root. (In this scenario, I wouldn't use the onboard fake-RAID but would use soft-RAID (i.e. 'mdadm').
Another Option:
I suspect that it would be easier to make Windows run from a RAID1 partition. (The BIOS would have no trouble handing-off to the bootloader but I haven't thought about making the bootloader and the Windows boot-up process respect the RAID setup.) I know that I get double read-bandwidth from my drives in either a RAID0 or RAID1 configuration and this is probably the most important concern for me.
Questions:
Has anyone made Windows boot from RAID? If I present the RAID drivers to Windows at install time (the F-key-for-disk-drivers prompt), does Windows know how to do the rest of the work and utilize a RAID0 partition for install and boot? Can this be done with RAID1? Can anyone offer me any advice or point me to resources that could help?
