Introduction
This document describes the operations of encrypting a removable media with McAfee
Agent, and accessing the files in the media on a computer with / without McAfee Agent.
2. Install McAfee Agent
Please note that the current version of the McAfee Agent only supports Windows
Platforms including Windows 7, Windows 8, and Windows 8.1. You can install the agent
and encrypt the USB devices on these platforms.
The Macintosh Platform can only read/write the McAfee encrypted USB device with OS X
10.8 or above.
2.1. Installation
2.1.1.
Install the McAfee Agent on your computer following the “Installation
Procedure for McAfee Agent” (on EPSS webpage:
http://epss.itsc.cuhk.edu.hk/data_encryption/installation.html).
2.1.2.
After the McAfee Agent is installed, you will find a McAfee icon on the
notification area.
2.2. Check the readiness of File and Removable Media Protection (FRP)
2.2.1.
Click on McAfee Agent, select ‘Manage Features’, then click ‘File and
Removable Media Protection’.
Page 3
User Manual for McAfee Agent v1.0
2.2.2.
The McAfee File and Removable Media Protection window will appear, check
the readiness of the following items:

Click ‘Available keys’ on the right hand side, a Personal Key for encryption
should be ready.

The ‘Initialize media’ under on the left menu should be in black color.
2.2.3.
If both are ready, please proceed to Section 3 “Encrypt a removable media”.
2.2.4.
If either one of the items is not ready, follow the steps below to make it ready:

3. Encrypt a removable media
After the McAfee Agent is installed and the FRP is ready, the data in the computer
will be protected from transferring to unprotected removable media. You can only
write the data to the removable media which is encrypted (protected) by the
McAfee Agent, otherwise, the device can just be read-only.
3.1. Plug in the removable media
Plug in the removable media into the computer which is going to encrypt the
device. Below McAfee message box will be popup which ask whether you want to
encrypt the USB removable media now.

If click ‘Yes’, it will initialize the encryption.

If click ‘No’, it will close the window and not start the encryption, and the
device will be read-only.
Please follow the steps in next Section 3.2 to determine the next action.
3.2. Check the storage space of removable media
The encryption process is different depending on the storage space of the media:
 If the total space of the removable media is smaller than or equal to (<=) 8GB,
the entire media has to be encrypted. Please refer to steps in Section 3.3.

If the total space of the removable media is larger than (>) 8GB, you can
determine and manage the size of encrypted space. Please refer to steps in
Section 3.4.
If you don’ t know the storage space of the removable media, then open Window
Explorer, right click the removable media drive and click ‘Properties’, then check
the total space of the device.

3.3. Encrypt a removable media <= 8GB

If there is data inside the removable media, you should:
o backup the existing data manually before the encryption: this can
ensure the data is backup successfully and the encryption process is
faster. Steps can be found in Section 3.3.1. [Recommended]
o backup the existing data via McAfee Agent before the encryption: the
encryption process will be far much longer than the approach in above
step, and may have risk during the process. Steps can be found in
Section 3.3.3.

If there is no data inside the removable media, please refer to steps in Section
3.3.2.
3.3.1. Backup existing data in the removable media

6. Best Practices
6.1. Editing files of the encrypted media
It is highly recommended to read and write files in your local computer rather
than do it directly in the encrypted media drive. It is because it will take longer
times to decrypt the file before you open it (especially for those files with large file
size), or encrypt the file whenever you save it if the tasks are performed directly in
the encrypted media.
So, in order to ensure the performance and the integrity of the file in the
encrypted media, please follow the steps below:
6.1.1.
Copy the file that you want to read or edit from encrypted media to your local
computer.
6.1.2.
Edit the file in local computer and save it.
6.1.3.
Copy the final updated file from local computer to the encrypted media.

6.2. Safely eject the removable media
No matter the removable media is encrypted or not encrypted, if you are going to
unplug it from the computer, it is very important to remove it safely by following
with the steps below, otherwise, data corruption could be caused.
6.2.1.
6.2.1.1.
In the notification area of the task bar, find the icon ‘Safely Remove Hardware
and Eject Media’.
Click on the icon and select the media which you want to eject.
