Defraggler stops after some time before 100% defrag is reached

Defraggler Defraggler Bug Reporting
1

After some time ( few hours) the defrag stops, thus before the counter gives 100% defrag.

At start the counts are for example 17 files with 473 fragments. Then after it stops and I again start it gives 15 and 469, then again it gives 33 and 549 and again 25 and 516. It never reaches 100% defrag. Even after a number of hours..

This is only on my data drive disk with many (some even large) files. On program drive C: it does reach 100%.

Is this normal or am I doing something wrong?

Hi OempaS, and welcome to the forum.

How big is the drive, and how much free space does it have? A minimum of about 12% is usually needed to defrag.

And you mention big files. If you're moving large files to the end of the drive (Defraggler settings), you may not have sufficient contiguous free space to be able to do that, hence Defraggler starting and not completing.

They're my thoughts off hand, maybe other members will have something different to offer.

I agree with Dennis here. Try seeing if there are any programs or files that are unneeded that you can delete.

Also, try turning off system restore & then turning it back on for that drive to free up space.

In Defraggler, under settings/options/advanced, try checkmarking:

"Turn off VSS (Volume Shadow Services) when defragmenting NTFS Volume", & also

"Use custom fragmentation settings" / Define, checkmark to exclude restore points & hibernation files

These settings should help out. Try it again & see what happens. If you have gi-huge files, you just may not have the free space needed to move them to consolidate properly.

Course, would be nice if this is the case, if Defraggler would give a user "Unable to move file... Not enough free space" in the future so they will know what is wrong.

Do you ever need system restore on a data drive ?

So far as I am aware S.R. is designed to IGNORE my document files,

and is a right pain with the massive system lockups when I choose to delete a jumbo sized *.PAF or *.EXE file which has served its purpose,

but Windows chooses to waste my time with an interception whilst it copies that file into the current restore point,

and when I regain control I find zero increase in free space - it is all wasted in the restore point.

Life became much sweeter when I limited S.R. to partition C:\ only.
