SYMPTOMS
========

A Windows NT 4.0 system may generate the following STOP code when an attempt is
made to read a corrupted floppy disk from Windows NT Explorer or My Computer.

  STOP 0x00000023 (0x000f00b5, 0xfc4af978, 0xfc4af7b4, 0xfeff4a6b)

- Run CHKDSK against the corrupted floppy disk from a command prompt before
  attempting to view the disk contents in Explorer.
