Disk defragmentation problem in C drive

Asked By jimmy_anderson 0 points N/A Posted on - 07/23/2011

Hey buddies,

I am having a problem with my C dive. I use to defragment all my hard disk drives every month.  This month when I tried to defragment the C drive, an error message comes out like “Windows cannot defragment this drive”. What sort of Message is this? Then I restarted my PC. But I got the same problem. I actually use the default defragmenter software for defragmenting.

Is it a problem which causes by virus? I appreciated any sort of help.

Thank you

Disk defragmentation problem in C drive

Can you try to run the hardware diagnostic test and check on the condition of your hard disk? Also, you can run chkdsk /r /f on the command prompt and check if you can see the drive under the Disk Management.

Another thing to check is the amount of free space you have on your hard disk. You need at least 15% in order to run the Defragmentation. You can also try the following:

1. Type diskmgmt.msc on the Start Menu search area. If it can detect the C: drive then run the check disk.

2. Run the Disk Defragmenter through the Command Prompt. Just type cmd on the search box and then right-click on the Command Prompt. Choose Run as Administrator and then type chkdsk C: /f /r and press enter.

3. Run the System File Checker to replace any corrupted or missing system files. Just type sfc /scannow on the command prompt.

Disk defragmentation problem in C drive

Hey bro,

How much free space do you have in the C: partition? You need a minimum of 15%.

Try running CCleaner, it has a handy registry tool to clean out any problems and then try to do it.  If your problems are not solved  then try a different defragmenter.

Disk defragmentation problem in C drive

Hi Jimmy,

This behavior can occur if you have the Speed Disk utility from Norton System Works 2000 installed on your system. This utility, if running in the background, blocks the use of the Disk Defragmenter tool.

This error can also occur if the file allocation table (FAT) is damaged. To resolve this behavior, if you have System Works, you must quit the Speed Disk utility and restart the Disk Defragmenter tool.

To repair the file allocation table, follow these steps:

1. Restart your computer in DOS, using the Windows Me Emergency Boot Disk (EBD).
2. At the command prompt type scan disk, and then press Enter.
3. The following message appears:
   The file allocation table FATs on the disk drive do not match. Scan disk has determined that copy 1 is the best copy. If you choose fix it, scan disk will replace copy 2 of FAT with copy 1.
4. Press Y, to answer Yes to the message.
5. Scan disk will replace your damaged FAT with the undamaged copy 1 of the FAT.

After Scan disk finishes repairing your hard disk, remove the Start up disk, and then restart your computer.

I hope this helps 🙂

Hello Dear,

Thanks that you have shared your problem with us.

Dear this problem is due to file system error.

Restart your computer.

When desktop comes in front of you then type CMD in RUN.

DOS will be opened. Then type "chkdsk" in that drive which generates error.

It will fix all file system errors. And then you can complete your desired process.

I hope it will help you.

Thanks
