Problem access to hard disk


Hi i have encrypted Partition0 on my hard disk,
after, in disk managment, i clicked MBR, and now i can't mount the partition....
I know the password (before it was in system favorite volumes and so it was mounted when Windows starts)
How i can remount it?

Have you tried mounting using the mount option button and selecting use embedded backup header?

Only if embedded backup won't work...

Which exact MBR option have you clicked? I accidently deleted my truecrypt partition once, so I was not able to mount it too, but I created simply tried to create it again and it worked.

Try to show us what exactly you did - on another disk, best on a flash drive without important data and make screenshots.

I have already tried to use embedded backup header, but it doesn`t work.
The steps for creating the volume with veracrypt (the hd was without any partition):
-Encrypt a non system partition/drive
-Volume Location: \Device\Harddisk1\Partition0
-Create encrypted volume and format it....
-Finally I loaded my data

After I open disk management and is appeared a screen like this: (and i had clicked on mbr)

Help please :(

The "Initialize Disk"-Dialog is shown by windows, if no MBR is present (GPT actually has a fake-MBR).
If you encrypted partition0, there was a MBR (otherwise partition0 would not exist) and windows would not show this dialogue!

So I guess you did not select \Device\Harddisk1\Partition0 for encryption but \Device\Harddisk1, is that possible?

In that case you have overwritten the volume header with the MBR and you are trying to mount the wrong volume.
If this is what you did you can try to delete the MBR and use the backup header of \Device\Harddisk1.
I'm not sure about the sizes of VC header and MBR, so I am not sure whether the first blocks of the actual partition have been overwriten as well.

I think you're wrong (it's possible to encrypt partition0):
How i can delete mbr? I think also that's impossible to mount \Device\Harddisk1 because when i try to mount \Device\Harddisk1, veracrypt say: Invalid handle.
I tried to create a new volume with disk manager and now i have
I wouldn't want to format it :(

You did exactly what I expected.
I was not aware that partition numbering in VC starts with 1.
If you selected HardDrive1, VC seems to show "Partition0", but in fact it does not use a partition.
(Maybe this should be changed as it confuses the user)
I think there must have been a warning as well. It's been some time since I used entire-drive-volumes and I don't have a second drive here to test with.

What you did is that you used the entire drive as a single "partition", then you have overwritten the header of this "partition" with a mbr.
You should stop editing around and create a backup of the entire drive first!

You cannot select the entire drive as volume in VC, as a mbr exists. If no MBR exists, you can select the entire drive in VC and mount.

  1. Backup entire drive
  2. delte mbr
  3. try mounting the HardDrive with the backup volume header

Sorry. I said "I think there must have been a warning as well." - It was, you screenshot it!
It exactly warns you about what your did:
"The OS may initialize the drive which may damage your volume"

So actually it is your fault - you have even been warned. Nevertheless I hope you get your data back.

First of all, thank you very much!!
Don t worry, i wouldn't do a backup...
Now i only want to test that you say... How i can delete mbr?
if it doesn't work, I will make a formatting.
I need the hard drive, and I haven't other attempts to do :(

Run admin shell (cmd)

use diskpart

enter "list disk" and find the number of your disk
enter "select disk X" where X is the number of your disk

be careful to select the right disk!

Okk... But first i must delete new volume that i had created?

squalo wrote Jan 14, 2016 at 12:06 AM

It doesn`t work :(.... i will format it!
