I agree with Mr Alpha - sounds like the boot sector is also involved in this. First get rid of XP by formatting the drive that it's on. Then format the drive that Vista is on. Finally, format the drive that the computer boots from (if it's different from the Vista and XP drives). You can do this with the Vista boot DVD. Once you choose the partition for Vista, you may want to also create a small (4 - 6 gB) partition at the beginning of one of the drives for use later on (see the last part of this post). It's important that this partition be the first one on that drive - you can then create a partition in the remaining space for storage.
FWIW - I suspect you've got 2 boot sectors - one on the hard disk that XP is installed on, and another on the hard disk that Vista's installed on.
Once that's done, have your SATA drivers ready on a floppy - and start to install Vista. When it asks if you want to load drivers for SATA/RAID/SCSI drivers, insert the floppy and let it load. Then finish the Vista installation.
If you get the error message again, please let us know the code that it gives. Most likely it's a driver issue with a piece of hardware, and I find that most times the drive issue is related to the SATA drivers.
Finally, once it's up and running, here's a tweak to make it a bit more peppy - go to Start and type in "sysdm.cpl" (without the quotes) and press Enter. Then click on the Advanced tab, then on the Performance Settings button, then on the next Advanced tab, then on the Virtual Memory Change button.
Set the paging file to "No Pagefile" on the C: drive, and set the Custom size on the 4 - 6 gB partition to be 2000 max and 2000 min. Then click on the Set button, Click OK to exit all of the dialogs and reboot for the changes to take effect. This'll help to reduce the hard disk bottleneck when using the pagefile - as the pagefile can operate independently of the OS since it's on another physical hard drive.
Thanks John for the response again,
Still having problems, before I go any further I have a few questions,
Was I supposed to format the drive that the O/S was loaded onto before actually loading Vista, or did the program do that automatically?
I think that the initial load of XP (remembering that I aborted this load) was incompletely loaded onto the 500 mb drive, I reformatted this drive (did not realize that it would take so long). I also believe that Vista was loaded onto this drive also. However, Vista still operates, albeit not too well, it still crashes. Is it possibel that part if not all of Vista was loaded elsewhere in the system? How would I be able to verify this?
I think that at this point I will re-format all 3 hard drives (2X250, 1X500) and start anew.
The boot order is set for DVD/CD player first, 500 drive second, 1 of the 250 drives third, then the second 250 drive last, is this correct?
Will I be able to reformat all drives using the cd that came with the drives (Western Digital) ? How do I go about doing this?
Please remember that I am a newbie, please bear with me, your patience so far is amazing......
Would you be able to provide a step by step guide for this, or direct me to a blog that would put this in laymans terms?
