EMS Encrypted portable Drive files not accessible

I have a WD Ultra drive that I have plugged into an Dell encrypted laptop.   The portable drive was encrypted and I was able to move file to the drive with now issue.  Now when I plug the drive into any PC it caused Windows to crash and I am not able to access the files.  This happens on the original laptop and any other laptops. 

If I boot Win-10 in Safemode I can see the files and copy them to another drive.  I have also copied the core file "Accessencryptedfiles.exe" to my PC hard drive along with the '_EMS_Config_Data_dir".   The Accessencryptedfiles will not run in Safemode and when I try and run from the PC hard drive, it does not seem to run. 

I copied over a few of the files to the laptop core drive while in Safemode and when I try to access them after restarting it does not let me.   It errors and says the format is not accessible 

I can't copy these files again from the original PC as they are now gone.

Is there a way for me to copy these files off of the current portable drive and then access them with a recovery tool?  I have the password for the encryption.

Hi @Bad_Andy,

There are hidden system files on Dell Encrypted devices that if aren't moved with the data then our agent doesn't know how to interrupt the data and will cause you to see the "format not accessible" type errors.  As long as the core data on the USB drive has not been modified we should be able to recover it using the process and tools described below.

To recovery the USB drive you can follow Chapter 2 of the following guide https://dl.dell.com/content/manual82761482-encryption-recovery-v11-4.pdf?language=en-us&ps=true and the recovery tools can be downloaded using this link https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=nkf08&oscode=wt64a&productcode=dell-data-protection-encryption.  Using the CMGAU tool paired with your recovery file you should be able to mount the USB on a machine running Dell Encryption and access the data.
