SYMPTOMS
========

When you try to remove an IDE hard disk drive, you may receive the following
error message:

  STOP c000026c unknown hard error %systemroot%\system32\drivers\atapi.sys
  c0000221

If you remove the power from the drive and then restart the computer, you may
receive the following error message:

  STOP c000026c unknown hard error %systemroot%\system32\drivers\diskdump.sys
  c0000221

CAUSE
=====

This behavior can occur if the drive you are attempting to remove contains a
paging file.

RESOLUTION
==========

To resolve this behavior, move the paging file from the drive that you are
trying to remove to another drive, and then restart the computer.
