True Crypt is an Open-Source software that can be used to create encrypted containers on devices. One of the major advantages of True Crypt is that it can be used as a portable application which means that you can copy the True Crypt files on the USB device so that the software does not have to be installed on the computer system where the data is needed.

There is however the requirement that the user who wants to mount the True Crypt volume to get access to the data needs to have administrative rights to run the software. That is however the only requirement.

Download the True Crypt software and run the setup. The setup displays options to install or extract the contents. Choose the extract option and pick the USB device as the target. All the files needed to encrypt and decrypt data will be extracted to the USB device.

Run truecrypt.exe afterwards. We need to create an encrypted container on the USB device that can store the data that we want to protect. It is limited to the free space on the USB device.

Click on Create Volume in the main interface and select the option to create an encrypted file container. Use the standard volume type in the next screen. Now browse to the USB device and pick a random filename that should be used as the container. You can use any name or extension, it does not really matter, for example test.avi, test.txt or bigrar.rar.

Pick an encryption algorithm (AES is fine and fast) and a Hash Algorithm (SJA-512) and define the space on the device that you want to assign. Select a password (20+ chars are recommended, the more the securer). The volume (in this case the space that you have selected) will be formatted. Move the mouse around to create random information and click the format button in the end.

This completes the creation of the encrypted container on the device. You need to mount it whenever you are going to use it. This is done by executing True Crypt from the USB device, picking a drive letter and selecting the file that contains the encrypted container.

The last step would be to click on mount to enter the password that is needed for the data decryption.

The data will be secure whenever the container is not mounted on the computer system. That’s one of the safest ways of transporting data from location A to B. Got any questions? Let me know.

The owner of the USB stick can set it to display an email address or phone number that will be revealed when the finder double-clicks the drive or autostart kicks in. The protection is basic and does not keep anyone from fiddling around with the files if they are proficient enough to do that. It is still possible to copy files from the USB device in the same operating system.

It is therefor more of a friendly reminder than a protection that would keep users “who really want the data” away. The software program basically increases the chance that the USB stick will be returned to its rightful owner.

USB Lost and Found comes in a Pro version as well which adds one interesting additional feature. The Lock Down feature will lock the computer completely if the USB drive is accessed displaying a similar message with the owner’s contact information and a password form.

The password is selected during the setup of the protection. The best case scenario would be this. User A loses his USB device, maybe near a Brewers Fayre chain pub in Cannock, Staffordshire. User B walks along and finds the USB device, decides to connect it to his computer to see if he can find any information on the rightful owner. Or confidential government data that might be worth a ton.

After clicking on the USB device in Windows he will either be greeted with the Please return message or he will witness a computer lockdown displaying the password box and the phone number or email address that he has to call / write to to unlock the computer again.

User B will call, User A will either tell him the password directly or agree to meet User B to receive the USB stick in person giving him the password then. Worst case scenario is that a Linux or Mac OS user finds the USB device.

The last incident came to light this Sunday. The Times Online is reporting that an USB Stick was found outside a Brewers Fayre chain pub in Cannock, Staffordshire which contained confidential passwords, security software and the source code of the Government Gateway. The data on the stick could be used to access the personal details of more than 12 million individuals who registered on the system including names, addresses, national insurance numbers, credit card information or passwords.

The system had been shut down shortly after the USB stick was found (again) to protect the data of the citizens. According to government officials the system has not been breached by then. Even more pressing than the discovery of the data on the stick is the source code which could be used to exploit the system to a much larger extent.

Investigations are in full swing and should reveal additional information soon. Gordon Brown commented on the incident with the words: “It is important to recognize we cannot promise that every single item of information will always be safe because mistakes are made by human beings.”

The USB Drive Letter Manager runs as a Windows service that solves the problem of drive letter assignments between usb devices, subst folders and network shares by automatically checking if the drive letter has been assigned to the latter before assigning a drive letter to a new USB device.

The software program can reserve letters so that they are not used by local drives, assign letters only from a list of default drive letters and specifically assign drive letters to USB devices by placing an ini file in the device’s root directory.

Another interesting feature of USB Drive Letter Manager is the ability to remove drive letters of card reader slots as long as no card is inserted. If you ever connected a multi-slot card reader to Windows you might have noticed that each slots receives its own drive letter by default which can be a lot depending on the number of different card slots on the reader.

By default USB Drive Letter Manager is only making sure that no network shares or subst folder letters get assigned to a newly connected USB device. Everything else is handled by the USBDLM.INI file. Additional parameters are described on the homepage of the software.

What I did was to create a main folder on my E: drive which I named USB. I then assigned all my USB devices to subfolders of that folder which led to less confusion on my part. (Create the subfolders before continuing). Here is what I did after creating the folder structure.

Press Windows R, enter diskmgmt.msc and hit enter. This opens the Disk Management configuration that should display all drives and devices currently connected to your computer. Pick an USB device from the list and right-click that entry. Select Change Drive Letter and Paths from the menu.

This should open a new window that is displaying the current drive letter of the device and three buttons at the bottom which are named Add, Change and Remove.

Click on the Add button, select Mount into the following empty NTFS folder and click on browse. Now navigate to the subfolder that you want to assign the usb drive to and confirm the assignment. The USB drive will from now on be accessible from that folder as well if it is connected to the computer.

You can remove the drive letter if you want that by marking it in the main window and clicking on Remove.

By default USB devices are optimized for quick removal in Windows XP. If you want to format your USB device as NTFS you need to change that to optimize them for performance. This has however direct impact on how you remove the device from your system. You need to remove it safely if you really changed that option otherwise severe data loss might occur.

I don’t want to go deeper into the topic but I guess it does not make sense to format your USB device as NTFS considering the prospect of data loss if you miss to plug it off safely. Still it`s good to know I think.

It is possible to label USB devices, set them to autorun and copy files to and from. Backing up files is a standard operation that should be done by everyone who owns important files. To backup or restore the USB device you simply click on the Backup / Restore tab and select the USB device from the list.

After that you can choose to backup files or restore them. If you choose to restore them you can select that the USB device should be cleared of all data before the backup gets restored.

There is however a trick that enables many USB devices for Readyboost even though they did not pass the initial test. To do that do the following. Right-click the device that you want to use for Readyboost and select properties. Switch to the Readyboost tab and uncheck “Stop retesting this device when I plug it in”. The old test values are stored in the registry which means that we have to edit some settings there to make Vista believe that the USB device meets all of the requirements. Unplug the device from the computer before you proceed.

Go to the key HKLM (Local Machine) -> SOFTWARE -> Microsoft -> Windows NT -> CurrentVersion -> EMDgmt which displays a list of all known USB devices on your computer. Choose the one that you want to use for Readyboost and edit the following keys in the right pane:

• Device Status – Change that value to 2
• ReadSpeedKbs – Change the value to 1000
• WriteSpeedKbs – Change the value to 1000 as well

After that is done you can use the USB device for Readyboost.
