My C drive (8 gig max) has 12% of capacity left. I can not defrag the drive using Windows XP (requires 15%)i DO NOT WANT TO DELETE ANY EXISTING FILES ON THE DRIVE TO REACH 15%. Is it possible to replace the exiSting drive with a higher capacity drive and move over the existing C drive contents (Windows XP etc.)? If so, how can this be done.
