<p>My sister asked me to have a look at her notebook (a Medion Akoya P6612
with Windows Vista) because the CDROM drive wouldn’t work, and it was
not even displayed in the Windows Explorer. I looked into the Device
Manager and noticed that the CDROM device (TSSTCorp SN-S083a) was
displayed with a small yellow exclamation mark besides its icon, and it
said on the Properties page that the device could not be started and
referred to Code 39. Reinstalling the drivers had no effect, but after I
had a little chat with <a href="http://google.com/">Big Blue G</a>, I found a <a href="http://www.pchell.com/hardware/cd_drive_error_code_39.shtml">howto entry</a> which
suggested the following:</p>
<ol>
<li>Be logged in with an administrator account</li>
<li>Open the Registry Editor (choose it from the Start Menu or press
Win+R and type <code>regedit</code>)</li>
<li>Navigate to
<code>HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}</code></li>
<li>Then, in the right pane, delete all of the following keys:
<ul>
<li>UpperFilters</li>
<li>LowerFilters</li>
<li>UpperFilters.bak</li>
<li>LowerFilters.bak</li>
</ul></li>
<li>Restart your computer</li>
</ol>
<p>This worked fine for us.</p>
