How to access the encrypted external data SSD/HDD on any PC?

Next, you should open the encrypted external data SSD/HDD on a different PC to be able to copy files or create the sensible folder structure.

1. Power off your server by pressing the power button
2. Disconnect the external data SSD/HDD
3. Don`t connect the drive to your PC, yet
4. Download Veracrypt from here and install it on your PC (if needed, restart your PC)
5. Now, connect the drive to your PC (choose to not reformat the drive if you get a popup, that it must get reformatted)
   BTRFS on Windows (this section can be skipped on Linux)

   Since the Veracrypt drive is internally BTRFS formatted and you've probably not yet installed the Open Source BTRFS Windows driver, you probably need to install it first before you are able to access the drive via Veracrypt:

   1. Open this link: click here
   2. Download the latest btrfs-x.x.x.zip release file like e.g. btrfs-1.7.8.1.zip
   3. Extract the zip archive
   4. In the folder, right-click on the btrfs.inf file and select install (you might need to confirm that you want to execute the file and choose to trust the author) and confirm to reboot if you get asked to do so.
   5. After the restart, the driver might still not work if Secure Boot is enabled which is the case on most devices nowadays.
   6. In order to solve this, open regedit, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CI\Policy, create a new DWORD value, name it UpgradedSystem, set it to 1 and reboot another time (source)
   7. After the reboot, the driver should work correctly.
6. Open Veracrypt, select the drive, type in the password and wait until it is mounted to your system

Now you should be able to access the encrypted drive.
