For reasons that have to do with my silly RAID 5 (which has nothing to do with this post) I need to transfer my operating system from the hard drive it is on to a new hard drive. When I added the new hard drive it became drive D. I copy the partition and then extended it using partition magic. Then I restated my computer and unpluged the original operating system drive. It gets all the way to the starting windows screen and then hangs. So I plugged the original hard drive back in, but changed the boot priority. It booted from the new hard drive, but the new hard drive was still drive D so all the programs were running off the c drive since none of the references were changed. I can't change the drive letter in windows how ever much I try and my guess on why it didn't boot when I unplugged the main drive is that it was trying to boot as drive D.

How did you "copy the partition"? If you used imaging software and cloned the drive there should be no issue with drive letters.
Get your facts first, then you can distort them as you please.

I use Partition Magic 8.

If you copied the drive the system drive to a clean hard drive...it should have included all files necessary to boot the newer drive as a replacement for the old drive (and all programs, data files, etc.).

<<Then I restated my computer and unpluged the original operating system drive.>>

I guess that I don't understand this. To boot from the newer drive, just replace the older drive...don't add any other drives...and then boot to ensure that it truly is a replacement for your older drive. Since it's the only drive attached, it will automatically become C:, with your optical drive becoming the D: drive.

Once bootability is confirmed...you can add other drives, add the older drive as a secondary drive, create new partitions, etc. Drive letters assigned to these will follow the normal Windows pattern.

Since you are running a RAID 5 configuration you have atleast 3 drives installed, did you rebuild the array to include the new drive?

While I do not know that rebuilding it will make any difference with the drive letter assignment, I would check to see if you need to rebuild the array since you have replaced a drive that was part of your RAID. If you need to rebuild the array and don't, then your RAID will not be doing its thing anymore.
