Xen,
I also installed the 64 Bit XP Pro over the holidays but never got the BSOD.  I have 2 X Sata 2 drives on my machine.  1 for the 32 bit version and the other for the 64 bit.  Of course after I installed the 64 bit version, I had driver problems but eventually found them on the internet.  Now that you mentioned the Sata/Raid issues, I'm wondering why I didn't experience any problems.  I haven't been using the 64 Bit as of late and now I'm wondering if I'll experience problems later with that version.  I will get that program you mentioned just in case.  Thanks for the heads up.
