Solved HDD Fragmentation acceptable level?

Specs: Microsoft Windows XP Professional, 2.793 GHz / 3070 MB

Iam curious whats a acceptable level of fraggmatation on a 250G.B. 7200rpm H.D. ? Usally after I defragment my H.D. it will hover around 16-17% fraggmentation , I remember my previous PC had a 30G.B. Hard Drive and after defraggmenting it would be as low as 3% ! Now on my much larger drive when I start the process it would have as much as a 24% fragmented status. I use a freeware app called Defraggler or Windows built in defraggmenting utility. Anyone who's familar with both of these is the Defraggler really much better the the Windows defragger ? Thanks in advance for any and all input on this subject !

Fragmentation is an unfortunate side of effect of how file systems work & data is stored. Ideally, all the data for a specific file/program should be stored contiguously so that the drive head doesn't have to move all over the disk to read it. But very often, when programs are updated, the new data can't be stored along with the original, so it is placed somewhere else on the drive. Also, if you constantly move or delete files/programs, it leaves blank spots all over the drive. So when new files/programs are added, they are broken up & stored in these blanks spots. In other words, fragmentation is partially caused by the technology, but it's also caused by the user.

All you need to do is run "analyze" using the Windows defrag tool...if it says "you do not need to defrag this volume", you *should* be OK. But if you're not happy with Windows giving you that message when the frag percentage is 16-17%, go ahead & defrag.

BTW, if you use Defraggler, make sure to get the "slim" version which doesn't have the spyware.

Fragmentation of an HD isn't nearly as serious a problem as it is often thought to be. It can be a serious problem but that is really quite rare. A moderate level of fragmentation will have little impact on performance. The overall fragmentation level isn't really that meaningful. What is important is the fragmentation level of your most accessed files, but measuring that is not an easy thing to do.

Defraggler may do a better job that Windows defrag utility but the difference in real world performance is likely to be minimal.

This Microsoft Software is good for checking wether or not a Gefrag is required, normally up to 10% is acceptable....
