I wrote not long ago about the best way to upgrade disks when using RAID1.
I've now managed to copy all contents from my 2 original volumes, into 2 identical (but larger) volumes on the new larger disk. I used Ghost for this, by making a backup of first the system volume, then the data volume, storing them on a 3rd disk, and then using the "Restore" function in ghost to write the data to the 2 volumes on the new, larger disk.
My issue now, is to simply remove the original disk, and boot from the new disk. I first left all disks in the server, and attempted to modify the boot.ini file and boot from the new disk, but I stumbled onto hardware problems, Microsoft's website said it was driver related - so I used the Hardware manager util in Windows to find out which driver was being used on my SCSI controller, and then placed that onto my boot floppy, and renamed it to Ntbootdd.sys but I still received the error.
I then abandoned the boot.ini method, and simply swapped out the old small disk, and placed the newer larger disk in it's place and attempted to boot from that. I got a non-system disk message. I'm stuck.
Here is some misc info that may be useful:
