hello. i've installed a new internal drive without any problem. i named the new drive using an available letter and then copied my entire data drive onto it. what i'd like to do is rename the new drive to the drive letter i am currently using for my data so i don't have to remap all my programs (iTunes, Photoshop Elements, etc.). i renamed the old data drive first to free up the letter, which worked, but when i rebooted the computer the new drive disappeared. windows didn't see it at all. i renamed the old drive back to the original drive letter, rebooted, and the new drive showed up just as it was before. anyone know what's going on? can i do what i'm trying to do - assign the new drive to the old data drive letter once i free it up? should i have done the letter swap before i formatted and copied all the data? any help would be appreciated. thanks.
