    Unhappy Unlock encrypted partition and access data

    hello I have 2 hard disks- 128GB SSD, and 1TB. My system drive ( 128gb ssd) encrypted (during Ubuntu 18 installation).
    I tried to cancel the encryption, but it's failed, and my second disk (1TB) encrypted to, and my system can't boot. I used the fsck to fix- and now it's can only give me a grub command-line. I have the password of both (the same). I have used live ubuntu, and here the results:
    I have unlocked the 1TB- but I cant mount it and get access to my data.
    and get an error:
    mount /dev/sda4 /mnt
    mount: /mnt: unknown filesystem type 'crypto_LUKS'
    How can I get my data back?
    Second 128GB SSD drive is locked. I have the password- when I boot the system (before braked) I can unlock the 128 drive with the same password.
    But now I can't unlock the drive- here is the error:
    Some pictures of my disks system:
    I have installed win8 on 50GB partition, and try to use librecrypt and Ext2Read. Both cannot help me.
    I'd appreciate help

    Please do not add large images inline as you did in your post.

    You should use the Attachment icon (paperclip) in the toolbar of the New thread or Reply text box which will add a thumbnail of your image as I have done.

    Many users still have slow network speeds and limited or expensive bandwidth, and huge images are not comfortably viewed with small screens.

    With full drive encryption you also have to use LVM - logical volumes and then all your volumes are inside the physical partition. And you have to use LVM tools to manage those volumes.

    I do not know LVM, but saved some links.
