Windows Vista Defragmentation Features
section: windows, for your questions: KezNews forum, 8.10.2007
Although it is virtually handicapped in terms of the options it actually provides to the user in comparison to Windows XP, the hard disk defragmentation utility in Windows Vista is an evolution of the equivalent from the predecessor operating system.
But the enhancements come essentially under the hood of the tool. In this context, the actual defragmentation engine was tuned up, as well as the management of the fragmentation process.
"By default, the defrag tool only defragments files smaller than 64 megabytes (MB). Therefore, files larger than 64 MB are not moved unnecessarily. In earlier versions of Windows operating systems, if the defrag engine was in the middle of a large move request, it could take lots of time to cancel defragmentation. In Windows Vista, the defrag engine processes input and output requests in smaller portions. Therefore, you can avoid situations where the defrag engine is busy with processing large move requests when you cancel a defragmentation session", Microsoft explained.
Microsoft's vision with Disk Defragmenter in Vista was to introduce a tool that would perform its tasks automatically at intervals scheduled by default. In the end, the Redmond company aimed at delivering a tool that virtually takes the user out of the equation, automating the process entirely. On top of this, the new system memory management in Vista confines the defragmentation as a process with low priority designed not to impact the performance of the operating system.
"The defrag engine in Windows Vista does not affect the performance of other processes that are running on the computer. Other processes are not affected because defragmentation runs as a low priority process. And, defragmentation uses only minimal CPU resources and memory resources. If the system is using lots of CPU resources and memory resources, the defragmentation process may take a longer time to finish," Microsoft added.
Additional improvements are related to the minimum amount of free space required for the defragmentation, as well as the speed and overall performance of the process. Microsoft applauded the fact that defragmentation in Vista takes up to two or even three times less than in older versions of the Windows platform. Vista will even combine the Master File Table into a single unit if it is fragmented.
"You can now use Task Scheduler to schedule defragmentation. Therefore, you do not have to manually start defragmentation. By default, a task is created and is set to run at 1 A.M. on every Wednesday.
In shadow-copy-aware defragmentation, defragmentation uses Volume Shadow Copy Service (VSS) in-box software to optimize defragmentation. The VSS software minimizes copy-on-write change blocks. Shadow-copy-aware optimization slows down filling the difference area. This kind of optimization also slows down the reclaiming of old snapshots during defragmentation," the company said.

blah blah blah, i like them colourful defrag, when its all blue and green , am happy. i
like to see progress whenever something is going on. so i still want xp
didn't you know, swandike. big brother knows whats best for all of us. [rolleyes]
defrag on vista sux!!!
bring the colorful progress bars back!
f....
ing microbloat!!
vistas defragger is more efficient than xp's but you cry just because it has no progress
bar?
sad little bastards
jimmy you moron, a progress bar will show you how much defrag is complete. with vista,
your just left there sitting and waiting, wondering when its gonna finish, unlike xp, it
shows you a percentage too.
seriously, if you have nothing better to do when your defragging the hard drive, you must
be a very sad person.
my guess is that your a sad little basement dweller who
has a huge bottle of coke and a box of dirty tissues on standby.
you twat, what are you 13 years old or something, coming up with a lame insult like that.
don't you think some people would like to know how much their hard drive has
degragmented? i certainly would, instead of having to wait like a moron, which you like
doing. so if you wanna suc.k up to vista, by all means do so, i like to be more informed
on whats happening on my pc.
vulture403 calm down and go back to your tissues.
unlike you, my
defragmentation only takes about 10 minutes and that is on a 750gb hard drive... even then
i do something like play a game since my system doesn't su.ck ass like yours seems to.
forgot to mention, i am not using windows vista, i am using opensuse and windows xp
because vista su.cks for everything except office work.
10 minutes for 750gb, thats bull.
1) you probably dont have jack all on your hard
drive for it to defrag that quick, and 2) if you have common sense, you wouldnt play games
while defragging, coz then it wont degfragment all your files since some of them will be
in use coz your playing your game.
...
my specs....
intel core 2 quad qx6700
corsair 2gb
ddr3 twinx 8-8-8-24 timings overclocked
2x bfg nvidia 8800gtx's running in sli
seagate 750gb hdd plus 120gb western digital raptor as bootup
asus
xonar d2 7.1 sound
... maybe you should try running windows on something like
this.
to top all that i have a great technical knowledge and with my pc i
don't care if it takes a tad longer to defrag when only one of my cores is doing the
defragging while my other cores are processing the game.
learn to use processor
prioritization in windows...
bye bye now, and go back to those tissues that you are used to.
sorry man but i love vista. i had xp and quake 4 and stalker ran at around 40fps on max
settings on xp. using vista i have seen dramastic improvement from 40-125fps. thats
include anti-anilising 4x and at 1200x1024. soz but xp does not cut it for games.
whatever you can say, most of windows users, download external programs, cos windows is
bullshit.
