All in all it went pretty flawlessly, but I don't know if that's a
factor of the amount of research I did beforehand on the correct
steps. So on to "what I did!":
Installed the drive in to the cage and plugged in the red SATA cable
that came with the motherboard (MSI KT6V) and the power connector that
came directly from my new power supply. I also disconnected my
existing PATA drive (Western Digital WD800JB, 80GB/8MB Cache)
Went in to the BIOS settings and ensured that the boot order was
CDROM, BBS-0 (why BBS I'll never know, but my Maxtor disk appeared
there).
Put in a MaxBlast3 floppy disk (I tried using the bootable CD but I
use a USB mouse and it wasn't happy for some reason) and formatted the
new drive as one big 200GB NTFS partition (I do video editing using
EditStudio and DVD-LAB so I prefer NTFS for big capture files)
Installed a slipstreamed SP2 verson of XP Pro (apparently you have to
use at least an SP1 version of XP to install on to SATA properly -
however I wasn't willing to take the time to test with and without)
At the appropriate time hit F6 to install a SCSI/RAID driver (SATA
apparently appears as a SCSI disk) and put in the disk that came with
my motherboard.
Chose to leave the filesystem intact and installed as per normal.
After booting in to Window for the first time I then installed the
Maxtor Big Drive Enabler and everything seemed fine.
Since then I've rebooted lots of times and all seems fine (currently
have about 20GB free after a large capture from Sky+ so I guess I'm
past the 137GB limit )
The only outstanding issue is that after reinstalling my WD drive, I
can't boot in to Gentoo using XP's boot loader - only by using the F11
boot menu. For more information, see this
