Detecting and Repairing Disk Errors
NTFS was introduced and billed as a "robust and self-healing" file system, as opposed to FAT, which is not. All in all, we have to agree with Microsoft on this one. We have yet to see an NTFS partition go "sour" in any way, shape, or form. We've had NTFS partitions that would not boot and key system files that would not run, but for the most part, these errors were self-inflicted and usually brought on by playing with fire.
The disk repair program in Windows 7's GUI is called Error Checking. These are the command-line versions (stored in the %SystemRoot%\System32 folder):
• chkntfs.exe—Works with NTFS volumes and drives
• chkdsk.exe—Works with FAT/FAT32 partitions and drives
For a description of how each works, just add the normal /? switch or see Windows online help. The available commands enable you to turn automatic checking on and off, and repair a "dirty" (improperly shut down) drive at bootup.
