2nd Drive Will Not Unmount

I recently added a second internal hard drive to my G5. The original drive was 250GB and the new drive is 500GB. I wanted to transfer everything from the original drive over to the new drive, which I did by using SuperDuper! to make a clone and then made the boot disk the newer, 500GB drive. Everything seemed to be fine. I kept all the info on the old drive for a while just in case something went wrong, but everything's been smooth.

So today, I go to the old hard drive using Disk Utility and try to partition it, but it says that it can't unmount it. Then I tried just erasing the volume, but it says that it can't unmount and to close any open files or applications.

So my question is, how do I go about seeing what applications or files are open on that hard drive? I tried looking at Activity Monitor but I honestly am not even sure what I'm looking at there.

This sounds like something simple to me but I'm not sure what steps I should take next. Can someone help?

Thanks!
 
I don't know! I thought that when I copied everything onto the new drive, and made the new drive the startup drive, that meant that everything runs from the new drive, right? Or is there something I have to do to tell the computer to run the OS from the new drive?
 
Ok so, you copied all of yoour documents to the New 500 GB, then you installed a clean version of OS X from the disc? If you tried to copy the system software over, you can't do that, you have to do a clean install.
 
Well, I didn't copy the documents over, I used SuperDuper to clone the old drive, backed it up onto an external drive, and then restored it to the new drive and made the new drive the bootup drive. It must be okay because I've been booting up from this new drive for over a week.

I think I did find the problem, though: I found a couple of aliases on the new drive that were still pointing to an application on the old drive. I trashed those aliases, restarted the computer (booting to the new drive), and finally I was able to unmount and erase the old drive. Whew! I hate when stuff like this happens!

Thanks very much for your help!
 
Thats good, but I still wouldn't reccomend, just copying over the system, could make it unstable, just consisder reinstalling in the near future.
 
So if I wanted to do a clean install, would I just erase the drive, install just the OS from my install disk, add whatever updates, and then do a smart update from my backup drive to copy all the other files over?
