mediacheck verifies the md5sum of the iso contents<br>

If mediacheck is throwing an error there is a problem with the media.
It may appear the install was successful but it should be considered
suspect at best.<br>

<p class="MsoNormal">I believe the media check simply checks the
physical disk
(ie making sure it can read from all sectors, etc). If this is the
case
then it is entirely possible that the date required for the install is
not on a
part of the disc the media check detects as faulty.<o:p></o:p></p>

you burn to ISO, always make sure to verify the md5 sum. A corrupted

failed
install.<o:p></o:p></p>
