Although it is possible to boot from the DataTraveler, it is not a feature Kingston supports.These drives are intended as storage devices.

Unfortunately this unit does not have any security or write protection feature. If you receive a write protection message with this drive, check for the following:

1. Verify that you are allowed to write to removable storage devices. There may be a security setting in the OS that disables write access to removable storage devices.
2. Make sure you have not enabled write protection on the drive by using a third party software.
3. If none of the above apply, the drive may be defective. Contact Kingston Technical Support for further assistance.

To transfer files larger than 4GB, the DataTraveler must have a NTFS or exFAT file system. Unfortunately, the FAT32 file system is not capable of handling a single file larger than 4GB (to be exact, one byte less than 4GB). Follow the steps below to format the DataTraveler with an NTFS File system:

Warning, all data on the DataTraveler will be lost! Please backup the data on the DataTraveler before proceeding.

1. Locate My Computer (Computer in Vista and 7). Right-click on the Kingston drive and select Format.
2. Select NTFS or exFAT from the file system drop-down list.
3. Select Quick Format as the Format option and click Start.
   Note: If NTFS is not an available option, close the Format window and follow steps 4-9.
4. Right-click My Computer (Computer in Vista) and select Properties.
5. Select the Hardware tab and click Device Manager.
6. Expand Disk drives and right-click on the Kingston drive. Select Properties.
7. Click on the Policies tab and select "Optimize for performance."
8. Click OK.
9. Repeat steps 1-3.

Be aware MacOS 10.6.5 will support full read and write access to exFAT formatted drives. MacOS still has read only access to NTFS formatted drives.

Some devices (MP3 players, digital photo frames, etc) will not read NTFS or exFAT file systems.

Also Windows XP and Vista will require an update in order to access exFAT.

If you have data on the DataTraveler that is important to you, we strongly recommend that you use one of the two possible ways for data recovery (see below). Kingston does not offer data recovery services. For more information on our warranty policy please visit http://www.kingston.com/company/warranty.asp

1. Contact a company that specializes in data recovery services such as Driver Savers at www.drivesavers.com and Ontrack at www.ontrack.com just to name a couple or you can do a search on Google for data recovery.
2. Go to www.download.com and do a search for data recovery and download one of the many utilities for data recovery which are fairly simple to use. We suggest trying one of the free versions as they work just as well as the paid versions. However for the possibilities for this option to work, the computer must assign a drive letter to the device. Even so it's not a guarantee. If not then option #1 would be your best bet.

KDT-012611-GEN-25

Some of the flash storage device's listed capacity is used for formatting and other functions and thus is not available for data storage, therefore you will not see the full capacity.

When a flash storage device is manufactured, steps are taken to ensure that the device operates reliably and permits the host device (computer, digital camera, PDA, etc.) to access the memory cells; i.e., to store and retrieve data on the flash storage device. These steps, loosely called "formatting," utilize some of the memory cells within the device and thus reduce the capacity available for data storage by the end-user.

Formatting includes the following operations:

1. Testing each memory cell in the flash storage device.
2. Identifying all defective cells and taking steps to ensure that no data will be written to or read from a defective cell.
3. Reserving some cells to serve as "spares." Flash memory cells have a long but finite lifetime. Therefore, some cells are held in reserve to replace any memory cells that may fail over time.
4. Creating a File Allocation Table (FAT) or other directory. To enable flash storage devices to conveniently store and access customer files, a file management system must be created to allow any device or computer to identify the files stored in the flash storage device. The most common type of file management system for flash storage devices is the File Allocation Table (FAT), which is also used on hard drives.
5. Reserving some cells for use by the flash storage device's controller, e.g., for storing firmware updates and other controller-specific information.
6. Where applicable, reserving some cells for special features. For example, the specification for Secure Digital (SD) cards requires reserved areas to support special copy protection and security features.

1. The DataTraveler could be conflicting with a pre-assigned drive letter. To resolve, do the following (Do not do this for a "Privacy" drive that assigns two drive letters):

1. Insert the DataTraveler and open "Control Panel". Then open "Administrative Tools".

2. Open Computer Management

3. Select “Disk Management” on the left window pane.

4. Locate the DataTraveler on the right window pane.

5. Right-click on the drive and select “Change Drive Letter and Paths.”

6. Click Change and select a new drive letter from the drop-down box. Then click OK.

2. The DataTraveler may be conflicting with pre-installed software. Disable all applications running in the background prior to installation of the Data Traveler.

3. Make sure Windows, any USB controller drivers and the system BIOS for you computer is up to date.

4. If you have a desktop computer, make sure the DataTraveler is inserted directly into one of the main USB ports on the back of the PC. Front ports, keyboard ports or USB Hubs may not supply sufficient power for the High Speed DataTraveler to function properly.

5. Check for a possible conflict is another USB device such as a printer or USB card reader. Unplug the other USB device, insert the DataTraveler drive and restart the system. After the DataTraveler is configured you should then be able to connect the other USB device.

You may have formatted the drive with an exFAT file system while using Windows 7. In order to resolve, reformat the drive with the FAT32 or NTFS file system. You may also be able to update your operating system to be compatible with exFAT. But be aware some devices (MP3 players, digital photo frames, etc) will not read exFAT file system.

Windows assigns new drives to the next available physical drive. It will sometimes take the same drive letter as a network drive for this reason. This is a common problem with removable storage devices.

To resolve this go to control panel>administrative tools>computer management. Note the drives on the right window pane. See if the Kingston (x) is recognized. (x) denotes the drive letter that Windows assigned for the Data Traveler.

If the DataTraveler is using the same drive letter as one of the other drives, right click the Kingston Drive letter and click on "Change Drive letter and Paths".

On the next dialog box click on the "Change" button and assign a drive letter that is not currently being used.

Note: Do not manually change drive letters if you have a "Privacy" Data traveler that assigns two drive letters for the device.

Follow the steps below to format the DataTraveler with an NTFS File system using Windows PC.

Note: Admin rights are required.

1. Remove all other external flash devices from your computer.
2. Right-click My Computer (Computer in Vista) and select Manage.
