Ok guys, here is one for you.

I just upgraded from 2000 to XP Home. I had two HDDs.
When I upgraded to XP it would not reconize my 2nd drive
(which is a Western Digital 100G), there is about 70G of
data that I need to get. Ok, what I have done so far,
checked BIOS, BIOS sees the drive no problem. Also the
jumpers look correct from the diagram on the HDD. When I
get into XP it is not reconized. When I go into disk
Management it sees the disk, but says Disk 1  Dynamic and
then below that it says Foreign. I have no idea how to
fix this. I have checked on WD's website and after
looking for some kind of drivers they said contact
microsoft. So hopefully someone can help me. Thanks for
helping...
