I'm running win XP Home SP3 and like many I have been noticing that the latest version of Defraggler v2.09.391 seems to be running very slowly, at this point it's slower then windows built in defragmenter.
My drive is 160gb and is split in to 2 partitions, the main partition which is about 80gb has the OS on and the second partition which is about 70gb is for file storage so that if the OS messes up I can reinstall with out loosing my files.
Now the main partition that has the OS on has just had a fresh install of XP put on it so there is only about 30gb of date on that partition and only about 2.5gb of that date is actually fragmented meaning that it should take no more than about 15 minutes to defragment, if that, yet i've had this running for hours and it's still not done yet.
It seems to make no odds if I use fast defrag or normal defrag both run extremely slowly and it's taking an age to move even small files which ordinarily would be moved immediately so obviously something is wrong because Defraggler shouldn't be running that slow, granted defraging can be a slow process if the drive is heavily fragmented or quite full or both but neither of these things apply in this cast so i'd like to know what's going on because some how I doubt very much that this is a problem with my system as I'm not the only one who is seeing this issue.
Something else I've noticed as well is that the time remaining seems to be woefully inaccurate and and not even close to reality I've had it project a time remaining of 30 minutes only to still be waiting for Defraggler to finish 4 or 5 hours later.
I don't know what you have changed but what ever it is it's had a badly detrimental effect on the speed of the application and if i where you i'd get your programmers to go over the code with a fine tooth comb becaue somthing oviously isn't working as it should be.
If you need any info or what have you feel free to ask and i'll try my best to answer.
Have you tried defragging from file list?. I never use the DEFRAG (full) option. It's slow as hell because it tends to suffle all data around, even data that isn't fragmented.
yeah and that's slow as well, as a comparison I just ran Mydefrag on C:\ using System Disk Monthly which fully defrag's and optimizes your disk and that took like an hour or so to do the job when I tried to do that with defraggler it's was coming out at like 5 hours to do the job.
which further leads me to conclude that there is something wrong with defragglers code it could be something as simple as an error that's causing unnecessary processing loops that would be consistent with the behaviour I'm seeing, I've seen this problem before in other program and scripts and it can bring even the fastest application to it's knees.
Don't use the full defrag then. Also, keep in mind that speaking about other defragmenters could be ill-advised. And besides, MyDefrag is pretty outdated by now. And for me, the UI is ugly too. I used it sometimes and didn't impressed me. It tended to fragment the MFT on my partitions for some odd reason. Other than that, it's still a quite good (albeit outdated) product nonetheless.
I don't normally use my defrag either it’s just that in this case I couldn't get defraggler to do the job in a timely fashion which is unusually because normally it’s a fairly zippy application when the drive is only lightly fragmented even on full defrag.
what I don't understand is why it’s taking like 4 or 5 hours to do a full defrag when it should only take around an hour or so, 4 or 5 hours or more if the drive was heavily fragmented or quiet full maybe but not in this case not when there is so little data on the drive and not when the drive is only lightly fragmented strange ?!?!
oh well no matter hopfully somome will track down the cause of the problem and put it right and get Defraggler running at a decent speed again.
As a test to your (and other people's) "This Defrag takes too long" queries, I decided to see how long it takes windows 7's in-built defragger, on a minorly defragmented drive which is auto-defragged once a week (two days ago for the last time). I started this defrag four and a half hours ago and it is still defragging. I maintain what I've said time and time again proper defragging takes a dog's age. . . long time periods can be expected especially with hard drives that verge of 1/4, 1/2 or even 1 Terabyte.
My Operating System partition (30GB NTFS Win7 x86) takes about 2 minutes to defragment with Windows built-in defrag program. I have System Restore disabled. I am not using hibernation either. If I use defraggler in file mode it takes even less time. I also have windows built-in defrag scheduler disabled. I defragment quite often though.
Bigger partitions and data types require more time. So for starters it's a good idea to repartition your harddisk specially if it is HUGE (1 TB+).
OP said he had two 80 GB partitions. The first one being the OS. You should do a little cleanup first, get rid of temporary files and other garbage. It should not take that long for defragging 80 GB, unless the partition is pretty fragmented and you plan on moving every file out there. That's because I advise you to try the selected files approach on defraggler first and disregard the System Restore Points altogether (I think they cannot be defragmented by common means either). After quicking defragging files from the file list, try doing a boot-time defrag.
