>>hi all,
>>I am tyring to run defrag on a customers server over RD. there is about 17% free on the c drive and about 9% free on the d drive. when i run defrag on both it starts and finishes without giving any warnings and does defrag some files but it does not do the entire drive. on the d drive despite there being 9% free when you run the analysis first you cannot see any white space on the screne at all. the c drive is 10gb and the d is 22gb.

>You *might* not have enough freespace to do a proper defrag - I can't recall what the limits were.

Normally Win2000 and up warns you if free space is less than 15%.

Either way you are very low on free space for defrag to operate properly.

Windows defragger isn't very efficient and does not try to optimize free space, so multiple runs are recommended if you are having serious fragmentation issues.

Commercial defraggers work better in low free space conditions, and they can be tailored to optimize free space if desired. Some also can defrag pagefiles and MFT tables which can be very helpful.
