I know when I did it i didn't have much luck with the copy partition option, it said formating drive for over an hour when a drive format shouldn't take more than a few min. Plus to format and copy the C and E drives takes about 5-10 min. So when you know copying the F drive is gona take much more than 24 hours it's not such a big deal.
You can try the copy partition, i just had better luck with the hard drive upgrade.
