I recently ordered and received the above mentioned card and I have run into a bit of a problem. I installed the card and hooked up my 2 drives to it...the master drive into the blue port on the card and the slave into the white port on the card. I then fired up the machine and put the XP cd in to boot off of. I pressed F6 when prompted so I could load the driver for the RAID card. The driver loaded and the installation continued. It then came time to install XP and to accept the license agreement and then create a partition and so forth. The hard drive information is as follows. The master hard drive is a Western Digital WD400 40.0 GB 5400 RPM drive. The slave is a Western Digital WD450AA 45.0 GB 5400 RPM drive. I chose to create a 10 gig C:\ drive and pressed enter to install into that partition. I then got a message that the other hard drive needed to have a partition on it because some information needed to be written to it. So I created one big partition on the other drive and formatted it NTFS. The install process then let me format the 10 gig C:\ as NTFS also. The install process then proceeded to copy files and finish the install. The machine rebooted and when it tried to load the OS...I got this message..."Windows could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. Check boot path and disk hardware. Please check the Windows documentation about hardware disk configuration and your hardware reference manuals for additional information." and just stops right there. Now I read an article in PC Magazine about IDE RAID and it said the drives do not have to be the same size to use them like they do in a SCSI RAID configuration. I looked at the documentation that came with the RAID card and it had nothing in it related to this. Anyone have any ideas as to how to fix this problem? Any input would be appreciated...
