The File System Check Report indicates the number of errors on a diskette. All
values should be zero. Nonzero values indicate file corruption. Refer to the
description of these values and to the DOS events in the log to determine the
cause. The most common cause of file corruption is that DOS was interrupted
while writing to the diskette and was unable to complete its operation. This can
occur when the power resets, the router reboots, or Slot 2 is reset. You can avoid
corrupting files when performing these tasks by first entering the
unmount
command (described next), and making sure the system does not respond with an
error message indicating that a file is in use.
