We've seen this when security software blocks the users ability to write to CD/DVD's. Run gpedit.mscand go to Windows settings>security setting>local policies>security options and make sure Devices: Restrict CD-ROM access to locally logged-on user only is set to disabled.
Also, too many entries for mounted devices in older computers can cause this problem. When all the entries cleared the drive should work again. To do this, go to start and type regedit in the search field. Make sure to back up your registry before making any changes. Here are instructions for backing up your registry.

In the directory list on the left side, find the entry HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices. Remove all entries except for default (it won't let you anyway).
You can also look at Device Manager when the Data Traveler is connected to see if the drive comes up with any yellow exclamation marks. Uninstalling the device with the exclamation mark and scanning for new hardware sometimes will work as well. You may want to try this even if you do not see any yellow exclamation marks for this device. You will need to run the uninstall as the Admin to be able to perform this while logged-in as a non-Admin.
Also check the setting for your security programs (Norton, Symantec, etc).

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:

If you continue to have DataTraveler start up issues, you may need to disable or upgrade any third party hard disk encryption software. There are known compatibility issues with Guardian Edge Encryption Plus Hard Disk (EPHD) software and Kingston's secure USB drives. Please contact Guardian Edge for additional information.

This DataTraveler requires two consecutive drive letters AFTER the last physical disk that appears before the ‘gap’ in drive letter assignments (see figure below). This does NOT pertain to network shares because they are specific to user-profiles and not the system hardware profile itself, thus appearing available to the OS.
What this means is, Windows may assign the DataTraveler a drive letter that’s already in use by a network share or Universal Naming Convention (UNC) path, causing a drive letter conflict.If this happens, please consult your administrator or help desk department on changing drive letter assignments in Windows Disk Management (administrator privileges required.)
In this example, the DataTraveler uses drive F:, which is the first available drive letter after drive E: (the last physical disk before the drive letter gap.)Because letter G: is a network share and not part of the hardware profile, the DataTraveler may attempt to use it as its second drive letter, causing a conflict.
If there are no network shares on your system and the DataTraveler still won’t load, it is possible that a card reader, removable disk, or other previously-installed device is holding on to a drive-letter assignment and still causing a conflict.
Please note that Drive Letter Management, or DLM, has improved significantly in Windows XP SP3, Vista, and 7, so you may not come across this issue, but if you are unable to resolve the conflict, please contact Kingston’s Technical Support Department for further assistance.

This is a common Windows XP issue caused by a drive letter conflict. In configurations where the network drive letter(s) follow physical drive letters, Windows XP may assign newly inserted flash drives a drive letter that is already taken by a network share. For this reason, you need two free consecutive drive letters available after physical drive letters (such as system partition, and optical drives).
Administrative Users: The issue can be solved by manually changing the conflicting drive letter(s) of the flash drive in Disk Management, located in Control Panel -> Administrative Tools -> Computer Management. If the launcher does not auto-run, reinsert the drive or manually run the Launcher from the DTBB Launcher partition.
Non-Administrative Users: By default, non-administrative users cannot change drive letters for flash drives. Contact your IT department for 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.
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.

This may be due to a power limitation. Though some USB devices may work fine in these USB ports, USB High Speed devices and some Encrypted USB may require more power. In order to resolve this issue, we recommend inserting the drive directly into one of the main USB ports. These USB ports are usually located on the back of the tower or on the side of the laptop. If these ports are difficult to access we recommend a USB extension cable.

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):
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.
If none of the above apply, your USB DataTraveler drive may be defective. Please contact Kingston Technical Support for assistance.

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.

To resolve, make sure to insert the drive directly into the USB ports located on the computer. The USB ports found on the keyboard and some hubs may not supply sufficient power to properly operate the Kingston DataTraveler. Also, go to Finder>Preferences>Sidebar to ensure CD, DVD and iPod and External Disks are checked. If you have an Encrypted USB drive, please make sure you have the latest firmware. If the drive has the latest firmware and still is not recognized or not accessible on macOS, please contact technical support for assistance.

After formatting the DataTraveler in Mac OS X, the following symptoms may apply:
This is most likely a result of using the GUID partition table, which is the default partition table for Intel-based Macs. The GUID partition table is only supported in Windows Vista. Windows 7 and Windows XP do not support this file system. To resolve, you must erase the drive via Mac OS X with the appropriate options selected. Follow the steps below to erase your drive properly with Mac OS X.
After the format is complete, verify that the disk is now using MBR by looking at the "partition map scheme" in the lower right corner of the Disk Utility window. It should now display "Master Boot Record."
