No output for getdek / decrypt WD My Book Essentials 3TB JMicron chip

Hi everyone,

I have a WD My Book Essentials 3TB that I am hoping to retrieve data from. When connected, it frequently disconnects and sometimes becomes undetectable. A lot of research later, I've deduced that it was due to the PCB. I took it to a local IT technician who managed to take it out of its enclosure and confirmed it was indeed a PCB problem. I've tried to search for a replacement PCB (as it was one solution i came across) but unfortunately, the model of this hard disk is old so it's been a challenge looking for the part.

After more googling, I came across an option to decrypt the drive as a way to hopefully gain access to the data. I came across reallymine and my-linux-tools and became even more hopeful, and was also amazed at all the help given by both project developers. I am a complete newbie to the world of Linux but I managed to slowly figure things out and create a live boot of Ubuntu to get started (all for the sake of the hard disk). It's now connected to my laptop using a SATA connection cable.

I initially tried to follow themaddoctor's guide but I was not getting a similar output required from each command. The My Book that I have on hand uses the JMS538S chip. I've read and reread the PDF, googled foreign-sounding terms and basically tried my best to follow the guide but to no avail.

Not giving up, I decided to go down the path of reallymine. For someone who is new to Linux, I finally got it to run (at least I think I did), however when executing the command "sudo ./reallymine getdek /dev/sdc", it doesn't produce any output, same goes to the decrypt command. When I try to close the terminal, it says that it is still running. So I re-tried the command again and left it for more than an hour but still nothing appears. I'm not sure how long it should take but reading from past issues - it didn't seem to take long, then again I might be wrong.

How long should I leave the getdek command to run? And is there a way to check if the data are still intact?

I apologise in advance for potentially stupid questions and thank everyone for their time and whatever help I can get!
