I've read through everything here, but have a couple questions

NOTES...
No password, only the self encryption...
My 3tb WD MyBook... power crapped... I removed from the case and put into a new basic case...
I DID NOT plug it into Windows after reading on here.
I made a bootable USB with Ubuntu, and after plugged in the new enclosure and it did show up as "sdd"
Tomorrow I have a new 10TB HDD as well as a basic case to put it in (never buying another externall HD in a case after this), assuming this will be found as "sde"

I see some on here are using ddrescue then decrypting... some creating the image file directly from reallymine....

I get the command $ reallymine decrypt /dev/sdd decrypted.img but being as I only have Ubuntu on a USB, I feel I need to specify to decrypt to sde??? totallt unsure what to do with the image file that is created?

Or is it better to ddrescue to sde then decrypt the image also to sde? this needs to be readable from Windows when all is said and done and I really dont want to do anything that will make it harder.

I am 100% unfamiliar with linux commands...

Any and all help would be beyond appreciated!!!
