I have windows 98SE and a 30 GB seagate hard disk . I run diskeeper lite(free) for defragmenting the hard disk and I do it manually on daily basis. It only takes 4-5 minutes to complete. I am overall satisfied with the utility but still feel that it is not that good as normmal windows defragmenter was. I want to ask can I run windows normal defragmenter utility once or twice a month. Does the normal windows defragmenter utility remains active after we install this diskeeper lite . I could experiment but thought that I should ask first.
