Well, I think I've decided for PerfectDisk.
I will download the trial first. And some more questions, please help me again.
Do you recommend me to let it run in the background and defragment all the time? Or is it better for the hard disk to defragment it once or twice a month?
Does PerfectDisk have to install any other Windows tool or program or anything external at all? Any problems with Windows XP firewall? Do I have to update PerfectDisk later on? Are updates free?
Thank you!
