F/U HP 9134A HDD problem

Hello,

I want to give some follow up on my problem interfacing a 9134A HDD to my HP
85.

Nothing seemed to work and I was about to toss it when I decided to follow
the advice of Alex Knight and vp**.

Alex suggested removing the HDD and trying to initialize each one of the 4
logical drives with the HDD on it's side, "to loosen things up a bit".

I took the top off, and hey, does HP use the biggest darn capacitors you
have ever seen or what? There are two side by side capacitors in there that
look like sticks of dynamite.

Mindful of these I had the first screw holding the drive out when I noticed
under a big dust ball that the ribbon cable connection from the HDD to the
PCB was loose. I pushed it back on and to my delight everything now works
fine! After a little detailing she looks and works great.

Thanks again for your help.
