I currently have 2 hard drives on my PC > C drive + F drive. over the last 10 months ! my main Hard drive (C Drive) has not been running properly the problems I have been having with this drive is ....... 1. If I try to move any files from C drive to my other drive it makes my CPU usage go up to 100% and causes my PC to run really slowwww !!...... It could take me up to 2 hours just to transfer a 4GB DVD movie folder. 2. If I run a virus scan on C drive this can all so take up to 2 hours to fully scan and my PC runs really slowwwwww!! 3 If I try to burn a DVD movie that is stored on this drive it will make my CP usage go up to 100% and take 10 times longer to burn the movie. In short words my main C drive which has windows installed on is totaly useless and I cant use it any way. I have tried defragmenting it and checking it for erros etc but wot ever I do just doesnt seem to fix the problems. I have now decided that its time to replace this drive with a brand new 300GB hard drive (maxtor) what I am unsure about thou is that this C drive has windows XP installed on it any many many programes and software that I have paid for over the years. is it possible to just transfer everything from C drive to this new maztor hard drive, then restart my PC and windows XP and all my software will all be fully working on this new maxtor drive ??. wot are my options here ??? thanks to nay 1 who can help me out !!
