Nice, and thank you very much for the guide !
Now I have a very strange behaviour here.
Since I installed the "Dual Hard Drive Kit" (the second cable basically) the FIRST SATA connector doesn't work any longer !
(I installed my second drive, wondered why it was not recognised, though it might even be broken 'till I switched the two disks and found out now my new disk was recognised but the old one was no longer visible).
My main objective was to switch my old (slow !) 1TB disk for a new 2TB with 4GB SSD cache.
So that's done.
But any idea why the primary SATA connector would no longer work ?
Is there anything like "primary" and "slave" switch (sadly known in the PC world ...) I should worry about ?
TIA for you help, and best regards,
