I have a Compaque Presario that came with Vista Home Basic preinstaled.
I want to keep the Vista installation to play with, but I want run XP Pro
so I installed another hard drive and instlled XP on it. The XP drive is
an 80 gig Maxtor ATA, and the Vista drive is Hatachi Deskstar SATA 160
gig. My problem is XP sees the SATA as raw partition. No partitiones and
no data. Is that normal? Both drives are formated with NTFS

Did you set the Master/Slave DIP switches properly on each drive?

Yes. The SATA drive is on a totaly different bus and has not been changed
in any way. The ATA/IDE drive is setup as Master to a slave DVD RW on the
only IDE bus on the system. The computer has 4 SATA buses and only one
IDE. I also tried a Promise ATA controler card. It worked ok with the dvd
drive, but was real flaky with the hard drive. I would use another SATA
drive except I don't have one, and I'm not quite ready to get one yet.
It's not important that I make this work, I have other systems, and this
one works just fine except that I cant read the SATA drive, and I don't
want to loose the Vista installation on it by Formating it to see if it is
Vista or the different bus types causing the problem.

"Serial ATA is 100% software compatible with today's ATA, but has a much
lower pin count, enabling thinner, more flexible
cables."

I believe that this is caused by a difference in file system
types between XP and Vista alltho both report NTFS in drive properties.
Checking this whyle each is running with the other drive disconnected.
If it's not file system then it must be BIOS related. I wondered if anyone
has seen this problem before or if anyone has tried to run XP as boot
drive with a Vista drive secondary. The SATA drive does not have Jumpers,
The cable only has one connector so no master/slave stuff. I'm choosing
which drive to boot in BIOS.

This link explains your problem I believe

You need to add XP to the dual boot using Vista as the 2nd OS not XP..ie
load XP then load Vista as dual boot, not the other way around..from what I
can recall it has been this way anytime you you add two MS OS as dual
boot...the later one is added 2nd.
