<br><br></blockquote></div>Not a bad scenario, good thinking. However, the box is built with all-new<br>
components, no old SCSI's. In a previous post, I have noted what my<br>
current thinking is on the most likely cause. With a little luck, I should have<br>
more information tomorrow and will post the findings here.<br>

"...never heard of Charlie Rose" - Hey, at least we know your not a liberal<br>
left-winger !<br>

Thanks for posting your thoughts on the out-of-sync troubles.<br>
