SYMPTOMS
========

When you run Microsoft Defragmenter (Defrag), you may receive the following
error message:

  Memory test failed at segment <address>

where the valid address range is 0000H-A000H.

CAUSE
=====

This error message may occur if you have defective memory.

RESOLUTION
==========

To correct this situation, have your memory tested and replaced.

MORE INFORMATION
================

Defrag performs a conventional memory test prior to defragmenting a drive by
allocating all available conventional memory. The memory test consists of
writing all (1) bits to memory and then all (0) bits. It verifies the write
succeeded by reading back the value and doing a comparison. If the comparison
fails, Defrag reports the failed segment number.
