8.1 Windows NT/2000: chkdsk

NICI 1.x versions are implemented as a kernel driver on Windows systems. Because of an improper registry configuration, the niciccs.sys kernel driver on Windows NT/2000 systems might prevent a check disk (chkdsk) from running during system reboot (initial blue screen). Alternatively, the system might try to run chkdsk on every system reboot. The NICI version 1.5.5 install fixed this problem. However, you can also check the Windows NT/2000 registry to make sure that your system does not have this problem. Check the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NICICCS key’s Start DWORD value. It must be set to 2 to prevent chkdsk volume access errors.
