Micco,
I don't know how to say this to you, but...
I think you installed it incorrectly.
I know the installation instructions seem like there were things left out, but that is why they recommend taking the keyboard to an authorized service center for the install. I'm obiviously working off the premise that the kit they sent you is fine. Everything regarding your hard drive should reassemble and have proper mounting if all the install instructions are followed correctly. YES! it is a RATHER (for Scott) difficult installation. It is critical that all the connections be made exactly as described by the install guide. Otherwise you will have problems accessing the hard drive for any reason. My recommendation is that you either take it to a service center or reattempt the install yourself keeping in mind how critical the connections are around the hard drive. I know that the orentation of the mounting plate for the hard drive is one of the more confusing changes that must be made. I know that you will really enjoy the interface once you have it up and running. Good Luck to you.
If you have any install questions regarding this product, feel free to e-mail me directly.
