I just installed a 250GB Seagate SATA drive to replace an 100GB IDE drive. I have an older Intel D850EMV2 motherboard so I'm using a PCI SATA host controller. I was able to load a fresh copy of XP pro onto using the "F6" trick to load the SATA controller drivers during the OS installation. The system recognizes and loads up fine as long as I'm using the drive exclusively. That is, when I attached the old IDE drive with the SATA drive together, the system hangs when the OS opens up (at the Windows XP logo). When I hook up either the IDE or the SATA drive by itself, windows has no problem loading. I've played with the BIOS, changing the order of the boot up drive, tried changing the jumpers of the IDE drive to different configs, flashed the latest BIOS, updated to the most recent driver for the controller,...nothing seems to work. Can someone please help?!!

Is the 100GB drive also a Seagate? If not then be advised that some drives just will not work together. Otherwise I would recheck the cables, jumpers and BIOS settings for the drives. There is a conflict somewhere there. Regards, Bryan

I may have actually figured this one out on my own. Apparently the conflict was in the BIOS where the system had trouble determining which drive to boot from. Even though the priority was set to boot from the SATA drive first, the motherboard maybe had to prioritize further down the line? Does this make any sense?!! There was another setting in the BIOS where I could change the IDE config so there was a delay before the system looks for the IDE drive. I played around with this and 4 seconds seems to have done the trick. Maybe will help someone else out with the same problem.
