Mixing HDD interfaces can cause some weird problems. When I got my first
IDE drives about 10 years ago, after a decade or more of SCSI-only, it took
a lot of fiddling with cables, BIOS settings and editing Boot.ini - and
several re-installs of Win2K! - to get my system running. And then every
hardware or OS update triggered another round of the same frustrations.
Since finally getting to all-SATA II a couple of years ago, thing have gone
much more smoothly. Since I have only a single computer, I don't have a
wide range of experience, but I can offer a few thoughts that may help.
Older motherboards insisted in booting from IDE, even if SCSI HDDs were
installed, too. Today's mobos should have updated BIOSes that handle this
much better; we don't often hear about such problems with mismatched HDD
interfaces. But yours may have some BIOS setting that needs to be set or
tweaked to skip your IDE drive and boot from the SATA drive where you have
your System Partition. The System Partition is typically the first
partition on the first HDD, but that can vary. And the definition of "first
HDD" can be unclear when there is a mix of IDE and SATA drives.
Both SCSI and SATA HDDs have often needed to have "mass storage drivers"
loaded from a floppy disk by pressing <F6> during the early part of Windows
Setup. Each successive version of Windows has had more "native" drivers,
and each generation of motherboards and chipsets has also had less
compatibility problems. But there is still the possibility that you need to
load drivers during the Setup process, especially if your System Partition
is not on that old standard IDE drive connected as the Master drive on the
first IDE channel.
I'm not a techie and I don't fully understand the "enumeration" process that
identifies hard drives and partitions during boot-up. I have found it very
difficult to reconcile the designations of drives among the BIOS, Disk
Management, Boot.ini and the BCD. "Disk 0" in Drive Management is not
always the HDD designated in the BIOS as the current boot device. And
neither is "rdisk(0)" in WinXP's Boot.ini.
I hope these comments help you find a solution. When you find it, please
post back for the benefit of others. Good luck.
