Can't get to disk defragment my laptop

Any ideas on how to defragment my Dell laptop? everytime I try I get the following message: 'disk defragmenter has detected that Chkdsk is scheduled to run on the volume: (C). Please run Chkdsk/f.' If I try to run a disk check, nothing happens either and get this message: C:/windows/system32/chkdsk.exe. The type of file system is NTFS. Cannot lock current drive. Chkdsk cannot run because the volume is in use by another process. Woulld you like to schedule this volume to be checked the next time the system restarts? Y/N
If I say Y, when restarting computer it still cannot perform degragmentation.
Any suggestions? Thanks so much

    Hi Joe and Pablo,

    Thanks for the assistance. I tried Auslogics Disk Defrag (just google it and you'll get the site), downloaded for free a defrag programme, and run it.

    Hope this helps others with the same problem.

    Kind regards

How To: Fix Windows Built in Defragmenter
Had the same problem, turns out that in SP2 you have to have "DCOM Server Process Launcher" enabled in administrative tools> services for the

· First open up a Command Prompt, this can be found at:
Start -> All Programs -> Accessories -> Command Prompt

· Change into your windows\system32 directory. Your windows directory will be either windows or winnt. Type:
cd \windows\system32

Register the defrag components, by typing:
regsvr32 dfrgsnap.dll
regsvr32 dfrgui.dll

At this stage, you may find the defragmenter works. If not, there is one more step you can do.

Using Windows Explorer browse to your windows\inf folder.
In there you will find a file called
dfrg.inf right click this file, and select Install.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

Try doing this:

Restart your computer and before windwos load, hit F8 and select Safe mode.
On safe mode do the chkdsk again.

Or use some utility program to defrag your disk like UBCD

Try using the FSUTIL DIRTY command to query and set the dirty bit on the volume. This essentially tells Windows that there is a file system error on the volume and it needs to run chkdsk next time.
At the command prompt, type FSUTIL DIRTY QUERY C: (or whatever your drive letter is) and get the status
Then type FSUTIL DIRTY SET C: (this sets the dirty bit).
Reboot. Chkdsk should run properly and reset the dirty bit automatically.

As for defragmentation, check out Diskeeper 2008. It's by far the best defragmenter available (Diskeeper invented the defragger for Windows!). No, it's not free, but you can get free trial versions from the Diskeeper site

How to defrag on acer extensa 5620

You can use the built-in Disk Defragmenter to Defragment your system.
To defragment your hard disk
  1. Open Disk Defragmenter by clicking the Start button. In the search box, type Disk Defragmenter, and then, in the list of results, click Disk Defragmenter.
  2. Under Current status, select the disk you want to defragment.
  3. To determine if the disk needs to be defragmented or not, click Analyze disk. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
Once Windows has finished analyzing the disk, you can check the percentage of fragmentation on the disk in the Last Run column. If the number is above 10%, you should defragment the disk.
4. Click Defragment disk. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

My N100 notebook is very slow in process

if it is a windows computer, try running defragmenter and disk cleanup.
to run defragmenter, in the search box in the start menu (in vista and windows 7) and search "defragmenter" select the c drive, and defragment it.. while you're at it, set up a weekly defragment with the defragmenter schedule.
To run disk cleanup, search for "disk cleanup" in the same search box. select the c drive, and check all the things you want to clean up.
you can always just do a scan with your antivirus to check if theres a virus slowing your system down.

Try disk cleanup, do anything to improve memory, turn off everything except defrag. Check task manager, it'll show you what's using memory.
