it'll fail. System and hidden files files will not be copied. You need to clone it using the new hard drive cloning software.
Windows Vista 32, hpdx2400 microtower came downgraded from Windows Vista to xp pro,intel pentium dual E2200,2.2ghz,3gbram, came with an 80GB hd which I ate up in a hurry. Got a 320gb and installed but was too chicken to try and make it the primary drive at that time. I am right now copying the C drive(oem) to my new 320, but the original c drive is partitioned into a d drive. I did not partition on my new drive. Problem??? or no problem. My plan as I had seen earlier from someone in the forum. Now I plan to unhook the original c drive from the sata0 and hook the new drive up to the Sata0 position. Good idea or not????
