Frequently Asked Questions

We've seen this happen when security software blocks the user's ability to write to CDs/DVDs. Run gpedit.msc and go to Windows Settings>Security Settings>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).

To transfer files larger than 4GB, the DataTraveler must have an 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 back up the data on the DataTraveler before proceeding.

  1. Type This PC in the Windows search bar. 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: macOS X has read-only access for drives formatted with NTFS file system. Additionally, some multi-media devices may not support NTFS.

As Windows is unable to format a drive over 32GB with FAT32, the use of third-party software is required. Although we cannot assist in acquiring or using third-party software to format a drive as FAT32, there are a number of free applications that can be found via Google or Bing search.

This is common for flash storage, whether internal SSD or external USB storage. It 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.

In most cases, it is normal for an external USB device to get warm or hot to the touch since the exterior shell helps cool the internal components by emitting heat into the air.

Some of the factors of a USB external device getting warm or hot:

    • Material: Metal flash drives and readers tend to get warmer while in use than other types of USB flash devices. This is simply because metal absorbs heat much more easily than materials like plastic do.
    • Environmental Temperature: If the host device or surrounding temperature is high, the drive's cooling capability decreases. USB drives often become warmer when used in hot environments or with warm devices.
      • File Transfers: Transferring large files or a high volume of files can raise the drive's temperature. Large files take longer to transfer, requiring more energy, thus generating more heat. Quick consecutive file transfers have the same effect as transferring large files, increasing the drive's temperature. During data transfer, the drive heats up internally and releases heat through its casing.
    Note: None of the above listed factors impact the functionality of the USB device.

    After the data transfer is complete, wait 30-60 seconds before removing the USB device from the host machine. This should provide enough time for the temperature of the USB device to cool.
