which is the best & the worse defrag?

Hi
which is the best & the worse defrag?

i mean the more safe and the less safe defrag that have you used?


please share with me


thanks have a nice day

 

I use the default defrag in WinXP but, I run it from a 2nd OS (also XP) or a boot CD like UBCD4Win. It seems to do a more thorough job when there are no files in use on the drive being defraged.

 

built in defragger:
pro's
- free
- light on resources

cons
- can only run one drive at a time (unless scheduled or ran from batch file)
- cant defrag mft (boot time)


other defraggers (perfectdisk/diskeeper/o&o)
pro's
- can do multiple drives
- boot time (mft defrags)
- automatic defragging
- pretty colours (seems most important to many people)

cons
- cost money
- require installation of services (so use ram)
- usually an annual fee to upgrade to latest editions

i did a basic test over a few days, and found zero difference in hard drive performance (over using the built in defragger) and actually percieved the pc to run laggy/slower with perfect disk 2008

 

The only defrag review that I know of is YONDER.

I have used JKDefrag for many months (it's FREE) and have never encountered a problem. Only GOOD results. However, I always use Image for Windiows to make a full disk image before doing a defrag. I image weekly, and before all major installs, uninstalls, or OS patches. Imaging to an external drive is THE best security, bar none.

 

May I ask why?

 

perfect screw up my pc one time in a offline defrag bad experiece

 

My brief thoughts on some defraggers:

PerfectDisk
Pro: thorough job of defragging
Con: slow

Diskeeper
Pro: fast, can adjust MFT
Con: not very thorough; sometimes chokes on big files

O&O
Pro: has multiple methods for defragging

UltimateDefrag
Pro: has multiple methods for defragging and lets you place files wherever you want
Con: boot defrag doesnt seem to work

JkDefrag
Pro: free/open-source, small size, multiple methods of defragging

Defraggler
Pro: free, thorough defrag, lets you easily defrag individual files only
Con: still developing; currently only a basic defragger

 

Why not?

After all, accidents do happen. Defraggers do LOTS of file moves - especially on highly fragged, crowded HardDrives. A screw-up of even 1 bit can cause a hard-to-find/hard-to-fix problem.

It's easy to image, so again I ask - why not?

 

Hi,

I use O&O Defrag for years and had never any problems, it was always fast and solid in all different versions.

The worst I haver ever used, was the late Norton Speed Disk.
It was running in circles for hours and and hours and suddenly it decided defrag is complet. But all I saw was a big mess with thousands of fragmented files.
Withal Speed disk was a good app in the early days.

Cheers

 

After trying out many trial versions, i finally settled for Diskeeper. The automatic defrag options work nice and havent had any issues so far.

 

DISKEEPER is a good choice however i tend to avoid defraggers that insist on running constantly and is why i retain the use of Ultimate Defrag exclusively.

Depends really on which defrag makes the best possible gains for you without sacrificing performance in my view.

 

which version have of ultimate defrag
to me it Defrag Gets Stuck At A Certain Percentage Number and Doesn't Proceed.

Personally i consider diskeeper not only the best ,but also i think the program is ahead of the time.Even if it constantly runs,on my pc it does use only a minimal amount of resourcesThe price however (100$),for the top version(pro premier which has frag shield),it is too much.I have the home version does a good job,but when i'll save some money i'll switch to o&o which iconsider second best.Perfect disk seemed slow on my xp,i did not try the new version hovever,now that i've switched to vista.The worst defrag i don't know .

 

I just had to fix a machine that was having a 100% cpu issue due to Diskeeper 2007. Annoyingly I recommended it to them.
I could not test Diskeeper 2008 as the owner of the machine was not prepared to pay for it. I have got them using JKdefrag (as the built in defragmentation tool fails to give satisfactory results) in the meantime, see if they get any luck from Diskeeper support.

I still personally use Diskeeper 10, works well enough for me to not want to upgrade to anything else , including Perfectdisk or newer versions of Diskeeper.
I did try Diskeeper 2007 , but not happy with the real-time defrag, as would not get enough idle time to keep my hdd defragmented during normal use.

I have performance issues with Perfectdisk 8, with the GUI, so I simply just closed the window to reclaim my cpu cycles - the drive would continue to defrag in the systray.

 

The best I have used till date has been PowerDefragmentor with contig.exe.

Just thought I'd share that brilliant piece of software since I do not see it mentioned.

 

You are correct there is zero difference in performance. My many posts on this topic have argued that there is not an iota of credible objective test data that shows defragging does anything to enhance disk performance. On my machines, Perfect Disk slowed down operations slightly.

 

And if you close your eyes real hard, no one can see you!

 

I never had a defrag which caused data corruption. If you use a defragger which uses the Microsoft API (nearly all of them) you shouldn't have problems. For extra safety, I store checksums (CRC32, MD5 and SHA256) of my images and check them after defragging or moving to another folder/drive. So, I even defrag my images with confidence.

 

and a defrag that crashes during moving data and that crash xp too??
i can say that can cause data corrupt

 

I never had a defrag that crashed. Microsoft's API allows to delete a file only if it's been copied successfully.
I don't do other activities while I'm defragging.

 

Possible incidents include a power failure, or a lightning-caused "blip" etc, or a lock-up for some reason. Any of these mis-haps (& others) CAN occur at some critical point such as just when a flag is about to be set, or just as the Master File Table is in process of being updated, etc. The fact that such hasn't yet happened to a given individual doesn't mean that they can't happen. My outfit's IT has had to restore an image after a defrag. It was he who taught me to image before doing a defrag. I do so at home. He does so at the office.

I repeat -- why NOT image?

 

I have an UPS.

Sometimes I'm really lazy

 

I don't have a UPS, but my computer does.

Me, too - that's why I image. It's much easier than reformating, & reinstalling OS plus all my programs. Just a 1-buttom click, then a short break for TV, & poof! It's done.

 

I call that smart !!

 

is somebody able to use the boot time defrag in ultimate defrag 1.72?
