Would greatly appreciate short points on PCB 100721570 as per attached

Fortunately, just found answer on current blog post!

Hello

Take a look please this article:
http://ts.acelab.eu.com/index.php?/ ... -f3-drives
Also you can contact Technical support department regarding this and other cases.

Great !

Article is gone. Please re-post

Sam, it's in the Blog: http://blog.acelab.eu.com/where-and ... rives.html

... unless it's a different article.

Thanks Larry. I just realized the original link pointed to the general shorting guide for F3 drives. I was hoping for a technique specific for this PCB/drive...I wasn't making any progress using the general guide.

I suspected that was the case. Sorry I couldn't help.

That's OK Larry... it was nice to hear from you at least

Enlarge picture at top; short points are 6th and 7th from the top on the left row. It's been a while since I did this but If not 6th and 7th, then 8th and 9th. You'll hear clicking when you hit the right points.

... or power the unmounted PCB and measure the voltage to ground of the obvious trace pair you think is the read/write channel. The read channel traces will have 0v and the write channel traces will have a small bias voltage, e.g., ca .5v.
