Problem

When connecting a removable media device, you may receive a pop-up box like the ones below:

1 : 

2:  

3:  

 

Cause

This dialog box may appear because:

Problem 1:

  • There are multiple partitions or volumes

Problem 2:

  • The removable media is exFAT fomatted

Problem 3:

  • The disk's partition scheme is not MBR and uses the GPT partition scheme
  • The drive has hardware encryption
  • It is an unknown or faulty disk

The most common reason for this dialog box, is that there are multiple partitions on the disk or the disk has hardware encryption already. 

 

Solutions

We recommend that you do not encrypt removable media if it contains your key-file back-up or administrator password.

Multiple Partitions

You can check to see if there are multiple partitions by doing the following:

  • Ensure you have a complete back-up of all data beforehand
  • Hold the Windows + R keys on your keyboard to bring up the Run box 
  • Type diskmgmt.msc in the Run box as shown below and click OK

  • As shown below, Disk 1 has two partitions, D: and F: (these may be different for you)

 

If your disk has multiple partitions, then you may follow the Microsoft article at the bottom of the page to delete them. 

 

How to change the partition scheme to MBR

Note: MBR devices can only be a maximum size of 2TB. This means that you can only use DESlock+ to encrypt your removable media device if it's 2TB or smaller. For more information, please read KB220 - What are the encryption size constraints?

  • Ensure you have a complete back-up of all data beforehand
  • Hold the Windows + R keys on your keyboard to bring up the Run box 
  • Type diskmgmt.msc in the Run box as shown above and click OK
  • Delete all but one partition (see the Microsoft article below)
  • Right-click the remaining partition on the disk and click Convert to MBR Disk

 

Hardware encryption

If hardware encryption is being used, you will not be able to use DESlock+ to encrypt the disk. You may click Don't show again for this drive to prevent future dialog boxes. 

 

What to do if the disk is faulty

Unfortunately, if the disk is faulty you will not be able to use DESlock+ to encrypt it. We recommend replacing a faulty device to prevent loss of data.

 

The removable media is exFAT formatted

To format the device follow the steps below:

  • Insert the device into your pc and click on Open folder to view files option.
  • Right click on your USB device and click on the Format option.
  • From the window, select a new file system i.e. FAT32 or NTFS from the drop down menu.
  • Click on Start and OK to commence the formatting proces.
  • Once the formatting has been completed click OK. 

Deleting partitions and formatting devices will erase the data that is contained, please ensure a back-up has been taken beforehand.
