Idle Defrag Recommendations

[REALfreaky]

Hey guys, I know that there's at least one other topic on here asking pretty much the same question, but I require an extra feature.

First, like the other topic, I would like a defrag tool that defrags my HD while the computer is idle for 10 minutes and stop defragging on un-idle.

But unlike the other topic, I would like it to check the current fragmentation percentage and only defrag is the fragmentation is over a certain level (say, 20% fragmentation). I'm hoping that something like this will keep my hard drive in tip-top shape while not shortening its life-span with unnecessary defrags.

Also, on a side note, I'm wondering if that having at least 15% free disk space really makes a difference or not; or does it only really require about double the size of the largest file on the disk?

Thanks in advance for any helpful replies. :)

I'm not sure if this product can meet all of your criteria, but I know that Diskeeper can automatically defragment your hard drive in the background (not entirely sure if it's idle-specific or not) using minimal system resources.

Diskeeper can defrag while you're using your pc and so can Raxco (my preferred choice).

I've heard diskeeper has issues with Vista though...

+1 for Diskeeper.

Also quite like Defraggler by Pirisoft (or CCleaner fame) http://www.defraggler.com/ although this is a manual operation.

I prefer the screensaver for JKDefrag.

Smart Defrag from iobit.com and its free.
