<p>I just did a hard drive scan on my 20 gig Ipod using the diagnostics testing menu. The ending message was "End scan. 112 RD fail Scan ng." </p>
<p>Does anyone have any idea what this means? I haven't been able to find a web site that gives a good answer to this question.</p>
<p>If it needs to be replaced, I have a performance service plan through Best Buy. Hopefully that plan works like that said it will.</p>
