the built in defragger in xp is a stripped down version of executive software's diskkeeper. The full version has many options and is a good defragger. its only slow the first couple of time that you do it. if you defrag reguarly it will finish in a few minutes.
The best one (in my opinion) is PerfectDisk 2000. It's the only one that defragments all of the files (paging file, system files, etc...). It's fast, and it works great. If not, the second best in my opinion is Diskeeper. It works great, but the only problem is that it does not defragment all the files.
hi, I've just tried out the O&O Defrag V4 and the Diskeeper 7.
It seems to be quite slow at start for both of them. The O&O Defrag V4 have so many defrag method, so how do I know which one is good for my HDD?
