99% of the time the pin 1 is marked on the circuit side. Check if is there.
You may see a 1 and 33 on the component side indicating the pin position.

I can't  see anything written on the drive itself, and I don't know what model drive it is (since there is an Amigakit sticker over things)  And the cable will go on either way around.

It should;t break things if I get i wrong, but just in case ..

I'll flick Amiga kit an email and see if I get a reply this money ;-)
I have plugged backwards countless time and never damaged the MB or the drive. The pin signals are wired so damage can not be done.
The way you know the cable is backwards is that the LED is always lit, and it may take longer to boot from HD or see the insert workbench disk.
But most of the time pin 1 in on the inside of the drive. I just checked 3 drives and all 3 have pin 1 on the inside, not outside.
