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).

This is common for flash storage, whether internal SSD or external USB storage, and is due in part to a variance in how flash memory vs spinning platter hard drive manufacturers calculate megabyte. Hard drive manufacturers calculate a megabyte (or 1,000x1,000 bytes) as 1,000KBs, whereas the binary calculation for flash-based storage is 1,024KBs.
Example: For a 1TB flash-based storage device, Windows will calculate it as having a capacity of 931.32GB. (1,000,000,000,000÷1,024÷1,024÷1,024=931.32GB).
Furthermore, Kingston reserves some of the listed capacity for formatting and other functions such as firmware and/or controller-specific information, and thus some of the listed capacity is not available for data storage.

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.

The problem may be due to the update deleting your user Temp folder. The drive uses this when running the security software.
To access the location of this folder, you must first un-hide all files and folders. To un-hide the files and folders, right click on the Start button and select File Explorer, click on File at the top then on Change Folder and Search Options. Click on the View tab and select Show Hidden Files and Folders.
Once un-hid, go to the C: drive>Users>Username (where username should be your name)>App Data. If there is no file called Temp, create a new folder and name it Temp. Once this is done, try your drive again.

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.
Note: macOS X has read-only access for drives formatted with NTFS file system. Additionally, some multi-media devices may not support NTFS.
