Defrag question

[tacoeater]

I have a supposedly healthy 80 gig drive in one of my computers and when I defrag (with 47% available) i still end up with two big red bars. There is no error message or any other indication that i am seeing for that not to be converted to the pretty blue stuff. Anyone know why? Is there another (free) defragger which would be more thorough?
thanks,
Alan

Boot into safe made and try defragging there, and it may take care of those for you..

Did u run chkdsk before the defrag? Also the built in defragmenter doesnt defrag the MFT and paging file. Try this and see if it works for you, although i prefer the full version that has some cool scheduling features that let you set it to run in the background.

Diskeeper Lite doesn't defrag the MFT or pagefile either. You need the pay version to do that.

If you read the report after defrag, it will tell you what the fragmented files are. They are probably files in a different profile that the logged in profile doesn't have access to.
