My computer will not defragment, it runs for hours And nothing?

Answer 1

If you are using win9x, turn off the option to scan for errors first.
And try to leave the computer idle while you are defragging. Shut off all unneeded processes, and disable your real time checking on things like your virus scanner or spyware catcher.

Answer 2

Mine did that too! Turns out, the hard drive on my ol' desktop was just too darn full for defrag to run though it tried and tried and tried...I had to interrupt the defrag (cancel through Task Manager or reboot) and not try again and give up. I found out in my case if I couldn't get rid of enough files to make room for a defrag it'd never work!

Answer 3

Defragmenting in a long process.

Takes up to 10 hours on a not used computer

Do not use your computer during defragmentation. Saving something on the hard drives makes it start again at the begining

Answer 4

It's best to defragment a HD with at least 20% space free, since it moves data around the disk.

I'm going to assume this is the cause.

You can also try using a third-party program to defrag, like Norton's SpeedDisk (my favorite). You may get better results, I always did.

Answer 5

Get a new Defrag program.

Answer 6

before each and every thing, that's an older device - Pentium II (400MHz) and 128 MB (SDRAM - upgradeable to 320MB). Your expectancies of it won't be able to be very severe. it really isn't any longer to assert you won't be able to fix it up and use it for common surfing, some e mail, and document storage. So ok, it really is sort of uncertain to me even if you really bumped off those "7 viruses" - in case you probably did not get rid of, then the first situation you need to do is bypass ahead and get rid of. even with the undeniable fact that, once you think you've an contaminated device - you need to receive an antivirus onto a sparkling computing device and produce it over for utilization on the contaminated device by a flash rigidity. This device sounds slower than it could be. i'd concentration on getting it "sparkling" and then paintings from there. there are a selection of thoughts to attempt this. It relies upon how a lot paintings you want to positioned into this (utilizing this as a gaining knowledge of adventure or only like it UP). you need to take the "cleansing it with quite some equipment and utilities" route <---extra paintings, yet extra gaining knowledge of or you need to take the "only reinstall the OS (operating gadget)" route <--- a lot less paintings, swifter I only also study your further information and that i see it really is extra accessible that you'll opt to apply this as a gaining knowledge of adventure. if so, it really is tremendous. ignore concerning the U3 and word if it exhibits up in "My computing device" and open it from there.

Answer 7

Defrag is not running in normal mode because one of two things or both:

Your screen saver is coming on and interrupting it (defrag can't run if it is interrupted), or:

Your hard drive is low on resources (ram):

Solution:

Reboot your PC and when it is booting up press F8 repeatedly. You will see a menu, choose Safe Mode.

When logging in to safe mode, log in as Administrator. When at your Desktop (which will look very strange) run your Defrag there.

It should complete.

Answer 8

I've had the same problem, defragment in safe mode.

Answer 9

try defragging in safe mode
make sure your HDD isn't too full maybe move some data to another storage device...
