The nopdb.exe process is automatically installed by Norton Speed Disk, which is a part of Norton Utilities or Norton SystemWorks. The process is used to schedule the time when the Speed Disk Application is supposed to run on your PC. This Speed Disk application is used to defragment the hard disk of your PC.
The nopdb.exe file is usually found in Windows NT4, Windows 2000, Windows XP, and Windows 2003 operating systems. By default, the file is located in a subfolder within
C:\Program Files. The known file sizes on Windows XP are 172065, 176193, 181416, 176161, 181672 and 176128 bytes. If you see a file alleging to be nopdb.exe but that does not fit known file sizes and locations, your best option would be to perform a quick virus and spyware scan of your system.
The nopdb.exe process runs at system Startup, and is notorious for consuming a large amount of CPU resources. Many users report that the process may consume up to 80% of CPU when it is running in the background. This extreme CPU usage is a cause of concern and irritation for several users.
The main cause of system slow down by the nopdb.exe process is that when Speed Disk runs, it starts sorting your hard disk volumes. The more information there is on the hard disk, the more work the process does. Although regular defragmentation can help, it still doesn’t completely resolve the issue of resource hogging.
You can change the default setting for nopdb.exe to Manual if it is causing a lot of trouble. However, it is recommended that you do not delete this file because deleting nopdb.exe will cause Speed Disk to stop functioning both in the automatic and manual modes. So, if you need to use Speed Disk once in a while, a better option is to set the process to Manual mode rather than to disable the process completely by deleting the nopdb.exe file.
You may use the following methods to either disable Speed Disk or set it to Manual mode.
Method 1: Steps to Disable Speed Disk
- Open Speed Disk.
- Click View and then select Schedule Options.
- Clear the Enable Schedule checkbox.
Method 2: Steps to Set Speed Disk to Manual
- Open Start menu and then select Control Panel.
- In the Control Panel, select Administrative Tools and then select Services.
- Locate Speed Disk and right-click on it.
- Select Manual and then click Stop.
- Click Apply and then click OK to save your changes and exit the Services dialog box.
