VeraCrypt / Forums / General Discussion: Can't do system encryption pretest.

Joshua King - 2017-02-06

I've been trying to use VeraCrypt to encrypt a asus transformer book for quite sometime now. I've made many attempts under different circumstances. Everytime I try though the process fails before the System Encryption Pretest can occur. My latest attempt was to do the process using the Administrator account rather than my own. I received the following error when trying to start the pretest.

The parameter is incorrect.
Source: VeraCrypt::File::Write:627

The "Source" section of this error is new but every time I've tried the process I always get the "This parameter is incorrect." bit. Any help would be great as I've been at this for a while but don't trust leaving the encryption of this device up to BitLocker.

Thanks.

  Hello, I have the same problem and I cannot solve it. Have you managed to solve it? If so, can you tell me how you have done it? Thank you!

I guess - ASUS transformer is new. It uses EFI based boot. Right?
You can check contents of ESP.
from admin cmd

mountvol o: /s

dir o:\

dir o:\EFI\

Yes, it does use UEFI. It uses 32bit efi images which I know VeraCrypt has support for.
Currently the efi directory is exactly what you would expect from a normal WIndows setup.
I've watched VeraCrypt change the efi section while setting up for the pretest but will revert it back after it fails.

  I suspect there is some antivirus software. It prevents to backup EFI\boot\bootia32.efi

    Hello, I have the same problem and I can not solve it. Can you help me?.
    
    I tried to enable the administrator account, disable UAC, mount EFI, assign a letter, disable TMP, disable all security software, disable secure boot, I do not know what else I should do.
    
    Hopefully they will join me and help me. Thank you very much!

You can search the forums for Acer to see the posts from other owners having issues. Here is a post that may help you.

  Hi, thanks for your response.
  
  Once I have encrypted the system with VeraCrypt, then I will be able to make the VeraCrypt loader as trusted. But right now is failing in the pre-test stage, it has not even been encrypted.
  
  The error message raises certain suspicions about what the real problem is. Maybe it's a permissions issue or attributes?

I think it's VeraCrypt software problem, because I've tried everything and the same error appears. Previously appeared error 627, now appears error 603. I have seen that other users also have the same problem.

  I have tested bitlocker and it works correctly, I have also tested a company's "Jetico" encryption software and it also works correctly, so I suspect it may be a VeraCrypt software problem. (Obviously I will not trust my security to Microsoft or Jetico).

  I am using the latest version available: https://sourceforge.net/projects/veracrypt/files/VeraCrypt%201.21/
  
  By the way, I think they have eliminated it.

It has occurred to me to encrypt the partition of Windows 8.1 from a GNU / Linux system, what do you think ?, this would work?
