Hi I accidentally ran Code: diskpart clean on an EFI partition that sat in front of a non-system drive veracrypt volume today. This caused the volume to become instantly dismounted. I made a grave mistake in re-initializing the disk in Code: diskmgmt and am unable to decrypt the partition as the Veracrypt volume header seems to have shifted. Also, about 2MB of data at the end of the Veracrypt volume partition has become zeroed out. As chance has it, I have two disks that are exact copies, so I was able to find the Veracrypt volume header offset from the working drive. This offset worked for recovering the dysfunctional drive's volume header, however, I am unsure as to how to proceed. If someone could help me verify the maths and solution going forward that would be terrific. My plan is to: 1) Make a full-disk copy to file. This will take about 12hrs with Testdisk. 2) Using HxD, make a file from the offset 210763776 through 5000980856831. This should amount to 5 000 770 093 055 bytes, which corresponds to Veracrypt's volume total size of 5000769830912 plus 256kB (262144). However, this becomes 5 000 770 093 056, which is one byte more. Is this okay? 3) Try to mount the file. 4) If mounting does not work, try to restore the volume header using the backup I created after finding the header at offset 210763776. What I am fearing is that I will be able to mount, but not decrypt the data. I have read that one can try to recover the file system. I am unsure what resided in the last 2MB of the partition. Hopefully nothing that will prevent me from decrypting. Any tips? I my strategy sound?
