Solving Hard-Drive Issues

NAVCE may fail to run properly if the disk is fragmented, has file allocation errors, or has corrupted system files. To solve these problems, consider the following commands:

• sfc /scannow Checks for corrupted system files (for example, ntdetect.com and bootsect.dos). Additional options are available to you when you use sfc, including:

  • /scanonce If you use this option, sfc will run at the next system reboot and scan all system files. However, the sfc command will not run on subsequent reboots.

  • /scanboot Has the system scan all system files each time the system is rebooted.

  • /cancel Removes all references to future scans, so the system will not use sfc automatically.

  • /quiet Has sfc conduct scans and replace files without user interaction.

  • /enable Enables Windows File Protection.

  • /purgecache Scans all files immediately and deletes all file caches so scans and repairs perform optimally.

  • /cachesize Determines the cache size used by sfc.

• chkdsk /f Locates bad sectors and file allocation information.

• You also should use disk-defragging applications to ensure your hard drive is working optimally. This is done by running the sfc /scannow command.

  Note	If you are wondering whether you have to issue similar commands on NAVCE servers as well, the answer is yes. However, clients tend to experience disk...
