    veracrypt partition GONE

    ok lets just point out i understand how powerful aes-256 is: its unbreakable... with 3x symmetric crypto algorithms in a cascade it provides stupid amounts of security. im totally aware of this fact, if a single byte of off of my keyfiles (i have copies) and a single bit of my password is off come hell or high water or the universe cooling that drive will not be decrypted ever.....

    I have used truecrypt for the better part of 10 years and never had this issue before. I fear the data is cryptoshredded aka really really gone.

    so here is the trouble:

    i wrote a 8 tb veracrypt volume its a seagate external desktop drive. Uses it for years works fine its reliable no issues. In the process of security upgrades of upgrading my system from truecrypt into veracrypt.
    make a veracrypt full disk image(temp storage): done
    mount truecrypt and copy files to temp storage in veracrypt: done
    deleted truecrypt volume and written over with veracrypt volume: done
    unmounted disk and remounted disk to validate the password works / keyfiles work: success
    copied files from veracrypt temp to seagate veracrypt: done
    unmounted disk and remounted disk to validate the password works / keyfiles work: success
    moved files from temp storage into new veracrypt full disk image: done
    unmounted veracrypt image and tested if i could remount: failure

    veracrypt only sees /dev/sde while the image is written to /dev/sde1 where did it go?


    Problem:
    VeraCrypt volume cannot be mounted; VeraCrypt reports "Incorrect password or not a VeraCrypt volume".
    Possible Cause:
    The volume header may have been damaged by a third-party application or malfunctioning hardware component.
    Possible Solutions:

    • You can try to restore the volume header from the backup embedded in the volume by following these steps:
      1. Run VeraCrypt.
      2. Click Select Device or Select File to select your volume.
      3. Select Tools > Restore Volume Header.



    gave error was not a valid volume so i can assume this means its hardware that is failing???? the data was really slow writing but thats normal.



    i triple checked password its correct / i checked hash auto detection and set to manual it was correct / i triple checked keyfiles for any issues and it was correct

    to attempt to debug i tried to backup the volume headers and got the bad password or not a valid volume error. The volume is encrypted but is missing sde1 partition mounting point.

    so i ruled out passwords and keyfiles it is correct. i then checked on another computer and got all identical behavior.



    veracrypt cant mount what does not exist. so where did /dev/sde1 go?

    to add insult to injury i was in the process of making a backup of the data.

    If using encryption, having excellent backups is mandatory, not optional.

    Not veracrypt, but LUKS encryption how-tos:


    Native is best. Stick with native Linux file systems and native linux encryption to avoid performance penalties and problems with permissions.
