Topic: VeraCrypt Encrypted Container mount error (Read 449 times)
This type of wrong password error can happen if something corrupted the volume header that is present at the begining of the disk.
For such situation, VeraCrypt stores a backup header at the end of the disk. So, the first thing to try is to mount the volume using the embedded backup header. To do so, click on "Mount Options" in the password dialog and check "use backup header embedded in volume if available" as shown in the screenshot below.
If this doesn't solve the problem, the issue could be linked to the fact that AutoMount is disabled in Windows (as explained in https://sourceforge.net/p/veracrypt/discussion/technical/thread/5948980c/#106d). In this case, you have to do the following:
In order to try to solve this, just enable AutoMount under Windows : start a command prompt as an Administrator ("Run as an Administrator"). In this command prompt, type : diskpart. Then after diskpart has started, type : AUTOMOUNT ENABLE
Restart Windows and try again.
Does any of this fix your problem?

No, I haven't. Bytheway I tried to change the password but doesn't worked for me.

I did not enter any value of PIM? What is this?
I do not use anything. But you can do something out of my way.
With which version did you create your two volumes?
Do you use automatic detection for the PRF or do you explicitly choose the right PRF? To avoid errors, set PRF selection to auto-detection.
Do you only use a password and you also have key file? What are the caractéristics of your password (length, composition,...)?
Did you enter a value of PIM?
Another user suggested to start by changing the password to a simple value (eg eeee) and then try to mount the volume with this simple password. Is it working for you? If so, you can set the password to a complex value and try again.
Thank you in advance for your feedback on these points.
Thanks for your tips. Can we talk on ICQ/skype?

Hello,
Yesterday I was trying to mount my encrypted container but without success. I was able to mount before yesterday and I am 1000% sure password is correct. Does anyone have solution for this problem?
Error code is: 8031 in ver.1.21
