Why wont my hard drive defrag?

January 5, 2011 at 09:01:58
Specs: Windows XP, 512 MB
I limit what web sites I go to anymore, as unless I figure out what's going on, I'm even about to partition and defragment my hard drive, then try and reinstall windows. In the past I've already partitioned and formatted the hard drive, and then I can't degf again. I'm losing my patience, as well as am just about to stop getting on my computer.

"about to partition and defragment my hard drive..then try.. reinstall windows"

It would appear whatever tool you are using for partitioning is having a problem.
You would not defrag a drive that had just been partitioned and formatted so your statement appears strange.

I would suggest you just use the xp install to partition and format the drive. It has worked every time for me and as a result defrag hasn't been an issue.

As an added suggestion you may wish to download the drive manufactures diagnostics and run them to make sure your drive is fit.

Have you tried Defrag., when you are in Windows Safe-Mode ???

You need at least 15% free space on the HDD.
Could try it while in Windows Safe-Mode.

I had partitioned and formatted the hard drive days ago. Just today I was once again unable to defragment my hard drive. I had also tried Diskkeeper, and had the same problem. Also, couldn't defragment in safe mode either. Seemed like no matter what I tried, safe mode, disabling everything under msconfig.exe... whatever... couldn't defragment my hard drive. Oh, and I'm only using about 90 % of my hard drive... I just reinstalled everything, but I bet soon I'll be in the same boat.

You can't defrag unless you have a minimum of 15% free space. You only have 10% free space which explains everything.

Perhaps its time to consider a larger hard drive.

There you go. You've used 90% of your hard disk, so you only have 10% left. As Chuck 2 says, defrag needs around 15% minimum to work. If you only have 10% free space then your hard disk is way too small or you're trying to install too much on it.

Edit: Oops - posted same details as Wanderer at the same time!

Now that I read my last post... what I meant is I have 90 % free space... I'm only using 10% sorry about the mixup.... I realize that, if I were using 90 % of the total hard drive space, I would be in trouble.... but I hardly have anything on my computer. Once again, I am only USING 10%.... I have 90 % free space.

Perhaps some services that are essential for defrag have been disabled? Under the services list check on and set the following to autostart: Task Scheduler, Disk Defragmenter, Remote Procedure Call (RPC), DCOM Server Process Launcher, RPC Endpoint Mapper.

Also, you may want to run chkdsk /r to scan for, and recover from disk errors. If the filesystem is corrupt defrag will not run.

As for the free space, 90% is plenty. But just FYI, the 15% requirement is only for the default Windows defragger. Newer third party auto defrag utilities are designed to work even in 2-3 % free space.
