I have XP SP3 on an Asus 900with freespace showing as 1.1GB/6.5 (i repartioned the ssd hard drive) which is 17%. However when I press defrag it says "You have less than 10% real free space available so defragging...(won't work as well)". How does this work. What do I need to do to make it work proper?
Don't defrag a SSD. It's pointless because of the way SSDs work, and it will greatly reduce its lifetime.

well the laptop will die before the ssd, that and i use the other partition more. but never the less. What is the cause for this message? does it only appear on ssd's? i don't see how your reply really helps me?
Well, I don't know why this message appears, but I can tell you defragging a SSD is pointless. No matter where a file or file fragment is on a SSD, it takes the same amount of time to find it. If you defrag it, the SSD will die before the laptop, since Defraggler's defrag algorithm tries to fill all holes and does not care about how many times it writes something on the disk
Besides, as Tom's Hardware says it, "An SSD?s firmware uses wear-leveling functionality to assign different locations for the data you push to the drive. Defragmenting the SSD would only jumble the data around more, for a ?sequential? file as seen by a software defragmenter doesn?t correspond to a sequential series of pages on an SSD block.".
fair enough, so then still the mystery remains of the pretend 9% freespace....
It might be related to NTFS-compressed files (they appear in blue in Windows Explorer). Defraggler doesn't handle those very well.
