This Stop message indicates that a problem occurred within Ntfs.sys (the driver file that allows the system to read and write to NTFS drives). Corruption in the NTFS file system or in blocks (sectors) on the hard disk can cause this error. Corrupted SCSI and EIDE drivers can also adversely affect the systems ability to read and write to disk, thus causing the error.
Check Event Viewer for error messages from SCSI and FASTFAT (System Log) or Autochk (Application Log) that help pinpoint the device or driver that is causing the error. Disable any virus scanners, backup programs, or disk defragmenter tools that continually monitor the system. Also run hardware diagnostics supplied by the system manufacturer. For details on these procedures, see the owners manual for your computer. Run Chkdsk /f /r to detect and resolve any file system structural corruption. You must restart the system before the disk scan begins on a system partition. If you create a Services for Macintosh volume on a large partition (7 gigabytes or larger) with a large number of files (at least 100,000) while the AppleTalk driver Apf.sys is loaded, the indexing routine consumes a large amount of nonpaged pool memory. If the nonpaged pool memory is completely depleted, this error can stop the system. However, during the indexing process, if the amount of available nonpaged pool memory is very low, another kernel-mode driver requiring nonpaged pool memory can also trigger this error. To resolve this error, either increase the amount of installed random access memory (RAM), which increases the quantity of nonpaged pool memory available to the kernel, or reduce the number of files on the Services for Macintosh volume.
