Retrieving data from dead iMac 2011

[Juicy Box]

While you are here learning about drive ports, this is an example of molex power port and two jumper pins being used:

Here is what a molex power cable looks like:

I am unsure of when it happened, but molex power ports were removed. I have some old SATA HDDs with the molex port, but they are probably 10-15 years old.

EDIT: these photo of the drives are upside down compared to the photo you posted, so the SATA data and power ports on the left.

Molex power ports probably the transitional period from IDE drives, all IDE drives I have used had Molex power connectors.

Well, the dock arrived yesterday and, thanks to all your advice I paid just 18 Dollars (15 Euros) and got this:

Sent from Madrid (I live in Spain) but, of course, made in China. And an impressive piece of kit it is too. Nicely packaged, aluminium housing, and complete with screwdriver and spare screw!
And, as you all said it would, it worked perfectly. I followed fishrrman's instructions in Post 2 but, in the event, the 'ignore ownership on this volume' box was already ticked. I spent a happy few hours working out the best way to get to my lost emails, managed to navigate to the V5 folder and discovered that the quickest way was just to copy them off to the desktop and sort them from there (I lost 2 years emails when I upgraded from High Sierra to Catalina). I now have a smart 'new' EHD, which, once I've checked there's nothing on there that I want, I shall format for future use.
A big THANK YOU for helping out this old silvery!
