    After entering my password for TC I receive the following message"
    E:/ is not accessible

    The file or directory is corrupted and unreadable

    I cloned the original external hard to another drive. When I try to open TC, I get the same error.
    TestDisk is at analyzing the drive is at 3%. So fare it has found 6 examples of Invalid FAT Boot Sector or Invalid NTFS or EXFAT boot errors.

    What should I do so I could possibly access my TC data again?

    When I try to open the E drive in WinHex it says the file or directory is corrupted and unreadable. Then when I click on OK it shows the files within that drive.

    Thank you for looking.

    Have you tried chkdsk?
    Open the TrueCrypt-GUI, rightclick on the mounted partition and select "Repair Filesystem"

    Ok, then some tools are needed for recovery of the files.
    I think you already found the thread where some rescue-tools are mentioned:
    https://www.wilderssecurity.com/threads/corrupt-encrypted-partition-i-used-truecrypt.267791/

    Someone was able to rescue files from not accessible volumes with "EaseUS Data Recovery":

    OK I will try this and I will let you know, I bought 2 HHD at 3 TB to make 2 clones of the affected drive.
    I already tried getdataback but it only find files not directories(I didn't let him finish yet) because I need my files to be organized in directories properly as I had Virtual Machines stored on the volume.

    I think also this is a big problem, as the recovery softwares find multiple NTFS partitions because of the virtual disks.

    I also don't find a good tutorial how to use TestDisk to fix boot sector, I will scan again with the TestDisk and I will upload a pictures here

    Thank you

    You may try: DMDE - DM Disk Editor and Data Recovery Software
    Make a full scan and you'll see what additional files it can find. Hopefully more than 60%
    Ideal is, if it can access your (hopefully not damaged) MFT Mirror (a backup of your currently damaged MFT)
