Hi: I just bought a Maxtor 80Gb HD. I took out my 40Gb made it a slave and put in the new one on master. I used the Maxtor CD and set it all up, formatted it and installed WINXP PRO. So, far so good. I went to my old drive which was still labeled C:\ (new 80GB drive was now G:\) took off everything I wanted on that drive and moved it over to the new drive. Then I went back to my my computer right clicked my old drive C:\ and formatted it. Hoping that with nothing on that drive or no OS on it when I rebooted my new drive would become C:\ and my old formatted one would now be G:\....................... apparently since I am here in this forum, that did not work. Now that I screwed this up, LOL, how do I get my old drive to become G:\ and my new one to become C:\ ?? Also, there is a D:\ drive, this drive is physically part of my 40GB drive, I reserved 5GB for storage, so C:\ and D:\ are all the 40GB HD. Any help would be greatly appreciated.
