Ok, that means that power is connected to the drive.

Can you check what kind of interface the drive have, does it have
. sata connectors https://en.wikipedia.org/wiki/Sata
. ide connectors, 40 pin header type
. or something else

Ok, let's stop here for the moment, we have to find out:
1, the drive's interface type
2, the data cable is attached correctly
3, what kernel you have

What kernel do you have, can you send me (privetly) its config file.

What happens if you do;
# modprobe sr_mod

# dpkg -l linux-image\*

# ls -l /boot
